Ischaemia-modified albumin in preeclampsia: A critical view
Abstract
The aim of the study was to compare ischaemia-modified albumin (IMA) levels, both original and corrected, in healthy pregnancies and pregnancies complicated with preeclampsia. Maternal and cord
blood samples from study (n ¼ 16) and control (n ¼ 17) groups were collected at the time of delivery.
IMA levels were given in absorbance units (ABSU). IMA levels, both original and corrected, were compared between study and control groups. No significant difference was found between maternal and
cord blood IMA levels between the study and control groups [1.0 (0.3–3.5) vs 1.2 (0.2–1.4) ABSU,
p ¼ .053 and 1.0 (0.1–2.2) vs 0.9 (0.4–3.6) ABSU, p ¼ .382, respectively]. The results were similar for
maternal IMA levels, after correction of IMA levels [1.1 (0.3–5.1) vs 1.2 (0.2–1.6) ABSU, p ¼ .292]. IMA is a
novel marker for ischaemia, without precise conclusions about its value in preeclampsia. An absolute
correction formula, considering all possible intervening factors, is required for more accurate results.
