Not all “good” cholesterol is equally good
HDL is reported as a single protective number. In reality it comes in subclasses, and they do not all protect you the same way. This test separates them.
The HDL Subfraction Test is an advanced cardiovascular blood test that analyses the different subclasses of HDL (“good”) cholesterol. It provides a more detailed assessment of cardiovascular health by measuring protective and potentially less protective HDL particles that cannot be distinguished by a standard cholesterol test.

Calculated free testosterone is below the lower reference limit. May be associated with symptoms of low testosterone including fatigue, low libido, and reduced energy.

Large HDL particles are generally the most protective. Small ones are less so. Two people with identical HDL can have very different actual protection.
A reassuring HDL number can hide an unfavourable subclass pattern. This is the detail routine lipid testing is not designed to pick up.

The HDL Subfraction Test provides a detailed analysis of HDL cholesterol by measuring the distribution of large, intermediate and small HDL particles. While standard cholesterol tests report a single HDL cholesterol value, this advanced test offers greater insight into HDL particle composition, which may provide additional information about cardiovascular health and lipid metabolism.
Large HDL particles are generally considered the most protective, while increased levels of small HDL particles may be associated with a higher risk of cardiovascular disease in some individuals. This test is particularly useful for people with a family history of heart disease, abnormal cholesterol levels, metabolic syndrome or those seeking a more comprehensive cardiovascular risk assessment. It is intended to complement, rather than replace, a standard lipid profile.
