RT Journal Article SR Electronic T1 Plasma iron values in National Blood Transfusion Service donors JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 680 OP 682 DO 10.1136/jcp.22.6.680 VO 22 IS 6 A1 E. A. French A1 Pushpa K. Sitlani YR 1969 UL http://jcp.bmj.com/content/22/6/680.abstract AB Haemoglobin, haematocrit, and plasma iron values were estimated on blood samples collected from 100 male and 113 female National Blood Transfusion Service blood donors, and from 83 male and 66 female age-matched control subjects. No significant differences in any of these values were found to exist between the donors and controls, and it is considered that the serum or plasma iron level is unsuitable for use as a screening test of early iron deficiency in donors.
