[Comparison of different methods for serum folate assay].
Folates were determined in 148 patient sera, using four different methods: a microbiological assay (Reference Method), two radioassays (Magic B12 FOL [NB] and SimulTRAC SNB no boil kits) and a non isotopic competition method (Magic Lite kit). Folate mean varied according to the methods 10.0 nmol.l-1 (reference method), 12.2 nmol.l-1 (Magic Lite), 8.7 nmol.l-1 (Magic B12 FOL [NB]) and 10.8 nmol.l-1 (SimulTRAC SNB NO boil). Poor correlations were also noted (0.83 < r < 0.95, figures 1 and 2). Differences between methods were explained according to the literature.
