Table 1 Serum folates (S. folate) performed at SBGH (1996-2004)

From: Ordering folate assays is no longer justified for investigation of anemias, in folic acid fortified countries

Year Number # of low S. folate % of low S. folate Mean S. Folate (nmol/L)
1996-8 2602 598 22.9% 17.1
1999-01 4464 242 5.20% 30.1
2002-04 24 0 0.0% 37.9
  1. The difference between the mean, number and percentage of low serum folates for the periods of 1996-98 and 1999-2001 is significant (P < 0.001) but between 1999-2001 and 2002-04 is not significant.
