Assessment of homocysteine status.
Patient/subject: Prandial status affects concentration, which increases slightly after a protein rich meal..
Matrix: Serum or EDTA plasma.
Volume: Minimum volume is 50 µL, but 200 µL is optimal and allows reanalysis.
Preparation and stability: total cysteine is stable.
Reported values: 150-400 µmol/L.
Reported value related to age and BMI.
Concentration increases in renal failure.
Intraclass correlation coefficient (ICC): 0.62.
