Automation of the assay of folate in serum and whole blood.

An automated system is described for the microbiological assay of serum and red cell folate concentrations using a chloramphenicol-resistant strain of L. casei. Both serum and whole-blood haemolysates are assayed directly without previous deproteinization. Results by this method are comparable to those obtained by standard manual folate assays… CONTINUE READING
