Abstract
Progesterone is a steroid hormone primarily associated with pregnancy. A simple, rapid, and reliable high-performance liquid chromatography (HPLC) method has been developed and validated for the quantification of progesterone in human plasma. The method consists of a simple liquid-liquid extraction of progesterone and internal standard (estriol) from human plasma using a mixture of hexane and diethyl ether. The chromatographic determination of progesterone was performed using an acetonitrile-water (70:30, v/v) mobile phase with a C18 reversed-phase column. The method achieved an extraction recovery of greater than 96.4% from spiked plasma samples. Intra- and inter-day precision were generally acceptable, with relative SD% less than ≤6.60% and accuracy (relative error %) better than 3.64%. The developed and validated method was used to successfully quantify progesterone levels in plasma samples collected from women during the third trimester of pregnancy. Furthermore, a statistical comparison was conducted between progesterone concentrations in plasma samples obtained from 2 groups of pregnant women: group 1 (n = 9) at 30-35 weeks and group 2 (n = 9) at 36-41 weeks. The developed and validated HPLC method described in this study enables the successful determination of progesterone in human plasma, offering advantages such as shorter analysis time, simplicity, cost-effectiveness, and potential routine use during pregnancy.
