Introduction: Spontaneous abortion (SA) is the most common complication in pregnancy. The aim of the study was to investigate the causality of selected genetic factors - Apolipoprotein E (Apo E) gene polymorphisms, factor V Leiden (FVL), Prothrombin (PT G20210A) and nongenetics factors - Thyroid stimulating hormone (TSH), free thyroxine (fT4), antibodies against thyroid peroxidase (a-TPO) in the role of early SA. Materials and methods: For genotyping of APO E polymorphism was used PCR-RFLP. The detection of mutations in genes FV and FII was performed using by HRM. Laboratory markers of thyroid (TSH, a-TPO and fT4) were determined by an automated analyzer using chemiluminescent immunoassay. Results: APOE genotypes of investigated group of 410 samples abortioned embryonic/ fetal tissues were not significantly different from 2 606 adult controls (P = 0.653). In observed infertile group of 75 women with isolated SA was FVL detected in heterozygous constitution with a prevalence of 12 %. The prevalence of FVL in a group of women with early insulated SA was significantly higher than 76 controls (12 % vs. 2.6 %, P = 0.031). The difference of PTG20210A prevalence between women with isolated SA and controls was not significant (4 % vs. 5.3 %, P = 1). The prevalence of elevated TSH levels (higher than 2.5...
