The standard components of a lipid panel include:. An at-home cholesterol test may involve some or all of these components. It is important to look closely at any at-home test to know exactly which cholesterol levels will be included in the test report. You can consider getting an at-home test if you are curious about your blood cholesterol.

This can provide information about your current cholesterol levels and may help initiate a more in-depth conversation with your doctor about heart health and wellness. At the same time, you should not have an at-home cholesterol test if you have concerns or symptoms related to your health.

In that case, you should talk with your doctor for specific guidance. Your doctor can also review the pros and cons of at-home cholesterol testing in your situation. It is important to consider the possible pros and cons of at-home cholesterol testing to determine if it is the right choice for you.

There are several different kinds of at-home cholesterol tests. All of the test options require a blood sample that is taken by pricking your finger with a very small needle. However, tests vary based on how and where that blood sample is analyzed. In a self-testanalysis of the blood sample happens at home, typically providing results within minutes.

Most cholesterol self-tests use a specialized test strip and a small device that can measure cholesterol levels. In a self-collection testyour blood sample must be mailed to a laboratory where it can be analyzed. Results are usually available within a few business days through a smartphone app or secure website.

Tests can also vary based on their specific components.

The exact results shown on your test will depend on which cholesterol levels were included in the test. Common target levels for different types of cholesterol include:. These numbers provide a general reference for target cholesterol levels, but targets for any individual can depend on their specific circumstances.

Low levels of HDL-C have also been tied to heart disease and other problems. Cholesterol tests should always be interpreted with your overall health in mind.

This means considering your age, sex, risk factors for cardiovascular problems, and health history. For this reason, it is best to discuss any cholesterol test results with a doctor who can best explain its significance in your case.

It is also important to remember that at-home testing may not use the same methods for measuring cholesterol that are used in tests ordered by your doctor.

As a result, you should talk to your doctor before comparing the results of an at-home test with results from prior cholesterol tests. Cholesterol testing is common and generally dependable as part of cardiovascular risk assessment.

Like any medical testing, though, cholesterol tests are not perfect. When properly performed, at-home cholesterol self-tests can be about as accurate as laboratory lab tests conducted with a blood draw.

However, products that are poorly manufactured or that provide inadequate instructions may suffer from reductions in accuracy.

For both in-lab and at-home cholesterol measurement, certain issues can influence the accuracy of the test:. For any questions about the accuracy of specific at-home tests, you can ask the test provider for available documentation related to the testing method and results accuracy.

Your doctor can also discuss any factors in your case that could affect cholesterol test results. Depending on your at-home cholesterol test results, you may need follow-up tests.

At-Home Cholesterol Testing

SRM c exists in a pure powdered form and is used to calibrate the methods used to measure total cholesterol. It can also serve as a benchmark to validate cholesterol results. Other labs that conduct research, such as the Centers for Disease Control and Prevention CDC , also can use the SRM to check against their own in-house working standards.

SRM c provides an analysis of the total cholesterol like SRM c but also is used to validate clinical procedures and methods for measuring the components of cholesterol known as high-density lipoprotein HDL and low-density lipoprotein LDL. SRM c also includes certified amounts of triglycerides, which are another type of fat found in blood.

At-home test kits involve a lancet to prick your finger to draw blood, and paper test strips. The small drop of blood is placed on the strip, which contains chemical enzymes including cholesterol esterase, cholesterol oxidase and cholesterol peroxidase that cause a similar reaction as the methods mentioned above.

Enzymes in the liquid react to the presence of cholesterol on the skin, causing the liquid to change color. The intensity of the light is then be measured using a device called a spectrophotometer. This new type of test is still in its infancy.

The U. Food and Drug Administration has approved at least one skin test , but this kind of test is generally a newer option that is not used as frequently compared to other cholesterol tests.

Instead, they give a general range within which your cholesterol lies. Clinics, diagnostic labs and hospitals can also measure just your total cholesterol level, but because of their more precise methods the results are specific to a number rather than a general range.

So, next time you sit down for a plate of scrambled eggs or take a bite of a cheeseburger, know that there are different ways to monitor your cholesterol levels at home.

Cholesterol is a type of fat that is part of all animal cells. Cholesterol is important Cholesterol is produced by the liver and also made by most cells in the body. We need a small amount of blood cholesterol because the body uses it to: build the structure of cell membranes make hormones like oestrogen, testosterone and adrenal hormones help your metabolism work efficiently, for example, cholesterol is essential for your body to produce vitamin D produce bile acids, which help the body digest fat and absorb important nutrients.

How cholesterol moves around the body Cholesterol is a waxy fat-like substance. It is carried around the body by 2 key transport systems in the blood, which include: Low-density lipoprotein LDL cholesterol — carries most of the cholesterol that is delivered to cells. How to check your cholesterol levels Your doctor can check your cholesterol levels through a blood test.

The blood test measures: total cholesterol HDL cholesterol LDL cholesterol triglycerides , another type of fat in the blood. There are no symptoms for high cholesterol. Safe blood cholesterol levels Many factors influence your cholesterol levels.

Total cholesterol levels should be lower than 5. Risk factors for high cholesterol There is no single cause of high cholesterol, but there are some controllable risk factors smoking and non-controllable risk factors age. Risk factors for high cholesterol include: age smoking lack of physical activity overweight or obesity family history unhealthy diet.

Effects of high cholesterol levels The liver is the main processing centre for cholesterol and dietary fat. Foods that contain cholesterol Research has shown that cholesterol in food has a neutral relationship with blood cholesterol levels.

Dietary tips to avoid cholesterol Following a healthy diet and lifestyle can help to lower your cholesterol levels over time, including: Increase the amount and variety of fresh fruit, vegetables and wholegrain foods you have each day.

People with high cholesterol should choose reduced fat varieties. Choose a variety of healthy proteins such as lean meat, chicken , seafood, legumes, nuts and seeds.

Also limit red meat to one to 3 times per week. Eat oily fish such as salmon, sardines and mackerel at least twice a week. Incorporate healthy fat choices such as nuts, seeds, avocados, olives and oils for cooking.

Cholesterol Tools and Resources

Discomfort is usually minor. To determine your cardiovascular risk, your doctor will consider your cholesterol test results in context with your age, sex and family history. Other risk factors , such as smoking, diabetes and high blood pressure, will be considered as well.

The American Heart Association recommends that all adults 20 or older have their cholesterol and other traditional risk factors checked every four to six years as long as their risk remains low. After age 40, your health care professional will also want to use an equation to calculate your year risk of having a heart attack or stroke.

People with cardiovascular disease, and those at elevated risk, may need their cholesterol and other risk factors assessed more often.

Your doctor will explain what your cholesterol levels mean and can discuss treatment options if your numbers are not where they should be. As noted, your cholesterol levels represent just one of many factors affecting your cardiovascular health. Your primary care physician will have a fuller understanding of your personal and family history, as well as any other risk factors that might apply.

If your cholesterol is checked at a public screening, they may measure your HDL cholesterol and total cholesterol. Getting your blood cholesterol, blood pressure, body mass index and fasting blood sugar measured regularly should be part of your overall personal care plan. Additional data points help to establish your cardiovascular risk.

This is particularly important for people who smoke, have other health conditions such as diabetes or inflammatory conditions, or have a family history of heart disease, high blood pressure or stroke.

Are the direct methods appropriate for research studies? In spite of the technical disadvantages of the Friedewald method—the need for fasting, the relatively high imprecision from the cumulative variations of the three underlying measurements, and the recognized limitations in certain patients—calculation is firmly entrenched in routine practice and will likely be displaced only if the homogeneous methods can demonstrate clear advantages in performance, overall cost-effectiveness, or other financial advantages.

Analytical performance is a key issue. All five homogeneous assays reported to date have current CRMLN certifications, indicating that at least one instrument application has demonstrated acceptable agreement with the RM on relatively normal specimens.

Three have been shown to give results comparable to the Friedewald calculation and appear to meet, at least in one study, NCEP performance criteria.

Other methods will require additional validation before definitive conclusions about performance can be made. Thus, some of the homogeneous assays could be considered to have demonstrated performance approximately equivalent to calculation in managing the majority of patients.

There are, however, important economic considerations to be addressed. Calculated LDL-C can be obtained without additional cost, provided the underlying values—TC, HDL-C, and TG—are measured, and with adoption of homogeneous methods for HDL-C, all three values are available simultaneously and by fully automated methods.

The incremental labor costs to include the homogeneous LDL-C assay with the current panel of three assays TC, TGs, and HDL-C are insignificant when a modern automated analyzer is used.

However, throughput will be decreased with four or even three assays per sample compared with one direct assay, a contribution to overall cost that is more difficult to quantify. Until reagent costs for the direct assays decrease, which might occur with increasing use, a cost advantage of the direct assay for LDL-C over the calculation is not obvious.

In considering whether the panel TC, TGs, and HDL-C could be replaced by a single direct LDL-C assay, one must recognize that lipid and lipoprotein analyses are performed primarily in patients for two reasons: a to screen for hyperlipidemia and b to monitor treatment of patients with hyperlipidemia.

In the first case, determination of LDL-C alone would not detect the risk associated with decreased HDL-C and increased TG concentrations. Although the latter could be detected by observation of turbidity in the specimen, most likely the HDL-C and, in most cases, the TGs would need to be measured in the initial workup.

In monitoring therapy, there will be patients, e. Nevertheless, considering that the common lipid-lowering agents not only reduce LDL-C but also affect TGs and HDL-C, the physician will, in many cases, want all of the values.

In summary, a direct measurement only could be adequate for managing therapy in some, but certainly not all, patients, and considering the lack of cost advantage, one must consider whether the occasional direct measurement might complicate practice guidelines and physician decisions about test ordering.

The Adult Treatment Panel III recommendation to include TC, HDL-C, and TGs as well as LDL-C in screening all adults 1 does not favor replacing calculation with a direct LDL-C measurement.

A thorough assessment of cost-effectiveness would also require consideration not only of the actual measurement costs, but also of the less tangible costs of measurement errors leading to inappropriate treatment decisions. In addition to the direct laboratory costs, there are other indirect costs associated with patient care that are much more challenging to quantify.

For example, some of the new homogeneous assays seem to be less affected by TGs than the calculation.

Furthermore, measurement in the postprandial state might be possible, despite the known changes that occur in lipoprotein composition after feeding, which would facilitate screening and managing of patients, reduce the need for repeated blood collections, and save time for clinicians, phlebotomists, and patients.

An objective assessment of such costs might support the direct measurement, but it would certainly require extensive additional studies, including consideration of outcomes. An overriding financial consideration in test-ordering practices is reimbursement programs in various countries.

A proposed change in reimbursement policy in the US, scheduled for implementation during the year , which would reimburse fewer lipid panels but more related individual tests, may favor adoption of the homogeneous assays for LDL-C irrespective of test performance and other economic considerations.

The homogeneous assays have been available for a relatively short time, and only limited data are available on their use. In the year , proficiency-testing programs in the US began including the homogeneous assays for LDL-C.

In addition to the CAP survey, which is the largest, other smaller programs, such as those of the New York State Department of Health, American Proficiency Institute, and American Association of Bioanalysts, also included data on the homogeneous LDL-C assays.

The remaining laboratories The homogeneous assays are relatively new, and many important performance issues have not been fully evaluated. Laboratories, especially those performing research investigations, long-term clinical trials, and supporting lipid treatment clinics will be cautious about adopting the homogeneous methods until more extensive validations have been completed.

The homogeneous methods should be evaluated under representative analytical conditions by comparison with accurate standardized BQ methods, using not only normal specimens but also a broad cross-section of unusual specimens, those at the extremes of the major lipoprotein class distributions and from individuals with conditions likely to alter lipoprotein characteristics children, elderly, diabetic patients, and patients with liver or kidney disease.

Essential in determining the appropriate use in patient characterization and management are studies comparing directly, in representative populations, the analytical performance and concordance in classification of patients by the homogeneous and calculation methods in relation to accurate BQ.

The homogeneous methods should also be compared with BQ in a broad cross-section of patients before and after treatment to demonstrate that changes appropriately monitor treatment effects.

LDL-C measurements in studies of unusual specimens must be performed in sufficient replicates to distinguish random errors from systematic or matrix-related separation differences. Highly discrepant specimens should be fully characterized to identify lipoprotein and matrix factors responsible for the differences, which might guide assay improvements.

Reliability of patient classification and monitoring of therapy using nonfasting specimens should be carefully evaluated.

The effects of freezing and prolonged storage of specimens should be determined for each of the homogeneous reagents. The new homogeneous assays for LDL-C, based on highly innovative assay principles, represent remarkable technologic breakthroughs with great potential for improving lipoprotein analysis, although concerns regarding their performance still exist.

The current routine method for LDL-C, the Friedewald calculation, only approximates LDL-C and is subject to well-established limitations.

The need for direct, accurate, precise, and convenient replacement methods has been recognized for many years. Studies to date suggest that the homogeneous assays are reasonably specific and free from major endogenous interferences, although additional validation will be needed before the methods can be confidently recommended for general use.

The homogeneous methods do appear to be significantly less susceptible to interference from increased TGs than the Friedewald calculation. Furthermore, if these assays could be shown to perform reliably in samples collected postprandially, the measurement of LDL-C will certainly become more convenient for the patient.

The methods may be appropriate for certain research studies, although specific validation under the conditions of the study is recommended. Although analytically more challenging and complex than the reasonably well-accepted homogeneous HDL-C assays, the direct LDL-C methods have the potential to significantly improve lipoprotein analyses and simplify the management of patients with HLP.

The methods certainly deserve further study to establish the most appropriate applications in quantifying LDL-C.
