Tests
The main circulating form of vitamin D and the standard measure of vitamin D status.
Indicators
The main circulating vitamin D metabolite — the standard measure of vitamin D status.

Indicators
Alpha-fetoprotein (609 aa, ~69 kDa) is encoded by the human AFP gene. This protein plays a role in the binding to copper, nickel, bilirubin and fatty acids in the fetal circulation.
Tests
The determination of the amount of apoptotic circulating tumor cells present in a sample.
Article
Research record from Blood Cancer J, 2026-06-27. PMID 42365009.
Indicators
Hemoglobin where the heme group has formed a stable complex with carbon monoxide (CO). This complex is produced after CO has been inhaled or as a byproduct of hemoglobin, protoporphyrin or dichloromethane catabolism. The heme-CO complex is approximately 200 times more stable than heme-oxygen complexes. Thus, high levels of carboxyhemoglobin in the circulation can lead to tissue hypoxia and death.
