From: Reference intervals for plasma sulfate and urinary sulfate excretion in pregnancy
Plasma sulfate and FEI sulfate levels in pregnant women. (A-B) Plasma sulfate levels and (C-D) FEI sulfate levels in (A, C) early (10-20 weeks) and (B, D) late (30-37 weeks) gestation. Individual data and median (bar). (E-F) Maternal plasma sulfate levels inversely correlate to FEI sulfate. Individual data and trend line for (E) early gestation, rho = -0.335, p < 0.001 and (F) late gestation, rho = -0.281, p = 0.004.
