How to Check Your Cholesterol at Home
Monitoring cholesterol levels is crucial for maintaining heart health and preventing cardiovascular diseases. With advancements in technology, several methods now allow individuals to check their cholesterol levels at home. This article explores the various home cholesterol testing options available, their accuracy, and their ease of use.
Fingerstick Cholesterol Self-Test
AccuMeter Cholesterol Self-Test
One of the most accessible methods for home cholesterol testing is the AccuMeter Cholesterol Self-Test. This test involves a simple fingerstick to obtain a blood sample, which is then analyzed using a test strip. A multicenter study evaluated the accuracy of this self-administered test among 486 untrained volunteers. The results showed a high correlation (r = 0.91) with the Abell-Kendall reference method, indicating that the AccuMeter provides reliable results. The study concluded that the AccuMeter test is a useful tool for increasing awareness of cholesterol levels and can be performed accurately by a large portion of untrained consumers.
Smartphone-Based Cholesterol Testing
Smartphone Accessory and App
Recent innovations have led to the development of smartphone accessories and applications that can measure cholesterol levels. These systems use a smartphone camera to image standard test strips, providing results within 60 seconds. Human trials have demonstrated that this method can accurately quantify total cholesterol levels in blood, making it a convenient and cost-effective option for home use. The widespread adoption of smartphones and advanced image processing technology enhances the accuracy and reproducibility of these tests across different devices.
Home Cholesterol Test Kits
Accuchek® Instant Plus® and Home Access® Instant Cholesterol Test
Home cholesterol test kits, such as the Accuchek® Instant Plus® and Home Access® Instant Cholesterol Test, are FDA-approved and available without a prescription. A study comparing these kits with clinical evaluations found that both kits provided accurate results, with the Accuchek® Instant Plus® showing a greater correlation with clinical results. However, user errors and misinterpretation of results remain concerns, emphasizing the importance of following instructions carefully.
Dried Blood Spot (DBS) Collection
Feasibility and Accuracy
Another method for home cholesterol testing involves the collection of dried blood spots (DBS). The Health Measures at Home Study evaluated the feasibility of incorporating DBS collection into population-based surveys. The study found that both field interviewers and health technicians could successfully collect DBS samples from over 95% of participants. While DBS results for hemoglobin A1c (HbA1c) were highly correlated with venous blood results (r=0.90), the correlation for total cholesterol was lower (r=0.65-0.67), indicating that DBS may not be as reliable for cholesterol testing compared to other methods.
Conclusion
Home cholesterol testing has become more accessible and accurate with advancements in technology. Options such as the AccuMeter Cholesterol Self-Test, smartphone-based testing, and home test kits provide reliable results when used correctly. However, it is essential to follow instructions carefully to avoid user errors and misinterpretation of results. Regular monitoring of cholesterol levels at home can be a valuable tool in managing heart health and preventing cardiovascular diseases.
