High-Density Lipoprotein Cholesterol Size
HDL C S
Description
"High-Density Lipoprotein (HDL) Cholesterol Size" test analyzes whether your HDL particles are large or small—key for understanding cardiovascular protection. Larger particles are considered more effective at removing cholesterol, while smaller ones may increase heart disease risk. Doctors recommend this test when deeper insight is needed beyond standard cholesterol panels. Results help refine care plans, including exercise, diet, or medications. Tracking HDL particle size provides a more complete picture of lipid health and supports proactive cardiovascular care.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
