Table 2 Baseline measures of iron and folate status under fasting conditions

From: Relative bioavailability of iron and folic acid from a new powdered supplement compared to a traditional tablet in pregnant women

  Mean ± SD
N = 18
Range % outside normal range Direction
Hemoglobin g/dL 12.6 ± 0.8 10.6–13.7 0*  
Serum Ferritin μg/L 14.1 ± 8.3 4.5–31.4 50** below
sTfR mg/L 3.2 ± 0.9 1.9–5.5 5.5*** above
Serum Iron μmol/L 14.0 ± 5.7 6.7–25.5 0****  
Plasma folate nmol/L 57.2 ± 19.2 17.6–102.2 72***** above
  1. n = 18. sTfR, serum transferrin receptor. *Hb cutoff during 2nd trimester is defined as 105 g/L and 110 g/L during third trimester[44] **Low ferritin values defined as <12 μg/L [43]. ***High sTfR values defined as 4.9 mg/L as per kit [21]. Serum iron for non-pregnant women is defined as 6.7–30.4 μmol/L[23] **** High serum folate values defined as >45.3 nmol/L [41].
