Question

erythrocytes can be used for evaluating vitaminB1 deficiency

Answer 1

The concentration of thiamine diphosphate (TDP) in erythrocytes is a useful index of thiamine( Vitamin B1) status.. Erythrocyte Transketolase(enzyme in erythrocytes) is other way of measuring thiamine deficiency or it's inactivity..Transketolase requires two cofactors, thiamine and magnesium and the laboratory test is designed to show their deficiency or abnormal chemistry by detecting the activity of enzyme.Hope it helps...
