Whole blood biotin

Typical reference interval values for whole blood biotin by a microbiological method are 0.5 to 2.20nmol/L, mean 1.31nmol/L. Deficiency is considered likely below 0.5 nmol/L. Reference values for other metabolites and fluids have been published elsewhere. ... [Pg.1109]

Quantitative assay of biotinidase activity including evaluation for the presence of a Km defect requires 1 ml of plasma. Serum samples can be also used. Biotin therapy does not affect the assay [ 32 ]. The activity in plasma may decrease during storage (see Pitfalls and Limitations , below). We recommend the use of ethylene-diami-netetraacetic acid (EDTA)-plasma separated from whole blood and assayed within... [Pg.255]
