the authors describe a modification of the instrumental parameters of the diamat fully automated hplc system for hb a ( 2 ) assay ( bio-rad laboratories , milan , italy ) in order to obtain simultaneous determination of hb a ( 2 ) and hb f.hb a ( 2 ) and hb f measurements are reproducible ( within-run cv 2.6 % , with hb a ( 2 ) 2.7 % ; 5.1 % , with hb f 1.3 % ) and accurate ( from a comparison with two microchromatographic techniques for hb a ( 2 ) : r = 0.9639 and 0.9755 ;
