Term Description

"Carnitine" is an alternative way to say total carnitines which = free carnitine + acylcarnitines, or stated another way, unesterified + esterified carnitine.
Source: Regenstrief LOINC

Both total L-carnitine and free carnitine levels in semen have been found to be positively correlated with number and motility of sperm, with decreased levels found in infertile patient groups (J Androl 2005;26:459-46). In addition there is evidence that dietary supplementation with L-carnitine can increase sperm quality.

Part Description

LP14482-1   Carnitine
Carnitine is used to mean total carnitines, because historically total carnitine was measured by heating up the sample and breaking off the esters which provided pure carnitine. (Carnitine is also a single molecule which is described as free carnitine - with the acronym, C0). Aclycarnitine is not a single moiety but rather describes all of the esterified carnitines.
So Total carnitine = free carnitine(C0) + acylcarnitine = esterified + unesterified carnitine. Source: Regenstrief Help
