Objectives (1) To investigate characteristics of hormonal vaginal cytology, progesteron and betaHCG concentration in the patients with threatened miscarriage in the first trimester; (2) To compare hormonal vaginal cytology results with concentration of progesterone and betaHCG in the same patient group. Subject and methods: Descriptive cross-sectional study was conducted on 100 pregnant women with symptoms of threatened miscarriage in the first trimester, who had received check-up and treatment at the National OBGYN Hospital for the period from January 2010 to June 2010. All of the pregnant women were undergone two quantitative tests in three-day interval of serum progesteron, betaHCG and hormonal vaginal cytology. Data was analyzed by Epi-lnfo 6.04. Results: There were 70 percent of the cases with abnormal betaHCG concentration; and 70 percent with low progesterone concentration. Woment with IA from 0-10 percent were majority with 58 percent; similarly, IP (62 percent). In the first check-up, number of women with abnormal IA, IP were low (respectively 42.0 percent and 38.0 percent). In the second test after three days, number of women with normal IA, IP was decreased (respectively 38.0 percent and 39.0 percent), while number with abnormal IA,IP was increased (62.0 percent and 61.0 percent). Cytology results shown that 30 percent of the cases were having basal cells, 35 percent having rhombus cells and only 14 percent having groups of detached cells. Percentage of women with normal IA and IP was lower in the women with decreased HCG, compared to the women with unchanged HCG (respectively from 62.0 percent to 38.0 percent and from 63.0 percent to 37.0 percent). In the women with decreased serum progesterone, percentage of women having normal IA, IP was also decreased (from 65.0 percent to 35.0 percent and from 61.0 percent to 39.0 percent. The results were compared and discussed.
