Measures all cholesterol-containing lipoproteins in a single reading (HDL, LDL and other particles combined). A broad cardiovascular health screen and practical starting point for people wanting a quick check or tracking whether overall cholesterol is trending in the right direction.

Measures thiamine diphosphate (TDP), the active form of vitamin B1, in red blood cells. Thiamine is involved in converting carbohydrates into energy and is important for nerve and heart function. Deficiency is associated with heavy alcohol use, poor dietary intake and malabsorption conditions.

Measures pyridoxal-5-phosphate (PLP), the active form of vitamin B6, in blood. B6 is involved in neurotransmitter production, haemoglobin synthesis and immune function. Both deficiency and high-dose excess can cause peripheral neuropathy, making testing useful for checking levels at both ends of the range.

Measures alpha-tocopherol (vitamin E) in blood. Vitamin E is a fat-soluble antioxidant protecting cell membranes and supporting immune and neurological function. Deficiency is uncommon with a balanced diet but can occur with fat malabsorption conditions, where prolonged deficiency may lead to peripheral neuropathy.
