Lactate plasma level as a potential biomarker in early diagnosis of ectopic pregnancy: A case‐control survey

Abstract

AbstractIntroductionA novel metabolomics survey proposed lactic acid as a diagnostic biomarker to detect ectopic pregnancy (EP). Here we investigate the plasma level of lactate for early diagnosis of EP as a potential biomarker.MethodsIn a case‐control study, the reproductive aged women with definite tubal EP (6–10 weeks' gestation), referred to our department during 2021–2022, considered as case group, and women with normal singleton pregnancy in the same gestational age as control group. After informed concept, demographic data (maternal and gestational age and parity) recorded and 5 mL venous blood samples were taken to detect the lactate plasma level. The data analyzed using SPSS software ver22.ResultsFinally, 95 participations (50 in case and 45 in control group) enrolled. The clinical results showed that the most of case group were aged more than 35 years old with had higher parity and body mass index, but, no statistically significant difference showed up. On the other hand, although the lactate level was slightly higher in women with EP, but, the plasma lactate level did not statistically differ between the two study groups. Also, the logistic regression showed no relationship between the demographic variables and the lactate plasma level.ConclusionIt seems that the plasma level of lactate cannot be a diagnostic biomarker for EP.
