Ovo je sajt na hrvatskom koji objašnjava jedan od razloga zašto se ovaj test radi. "Mjerenje razine homocisteina u krv je novi, potencijalni test koji spašava život."

Nivo homocisteina u plazmi može da se odredi pomoću kompleta sa dva ili sa tri reagensa. "The 3-Reagent Homocysteine Assay for SYNCHRONO and UniCelQ® and the AxisShield Liquid Stable (LS) 2-Part Homocysteine Reagent are both enzymatic assays for the quantitative determination of total homocysteine in human serum and plasma. The calibrator formulations are identical and although both assays use the same cycling enzyme assay technology, the number or reagents and reagent formulations are different."
