Haemoglobin levels according to age, haematocrit, transferrin and serum iron level in medical students of comparable socio-economic status.

1. The haemoglobin, haematocrit, transferrin and serum iron of a group of 418 healthy medical students, aging from 18 till 25 years, were determined. The mean Hb for the male students was 9.4 +/- 0.63 mmol/l, for the female students 8.7 +/- 0.56 mmol/l. 2. The correlations between Hb, Ht, SeFe and transferrin have been investigated. A positive correlation exists between Hb and SeFe and Ht and SeFe.
