One single hCG value does not tell you much about the viability of the pregnancy and there is a wide range of normal hCG levels in pregnancy. In fact, one of the problems with doing urine pregnancy testing is that many women who have irregular periods are unsure exactly when ovulation/ferti...
Samples were applied to single-use cassettes, which functioned via a two-site enzyme-linked immunosorbent assay (ELISA) method in 10–12 min, with a quantitative hCG range of 5–2,000 IU/L. Calibrators and controls for the device are traceable to target hCG concentrations defined using ...
It's important to note, however, that there's a wide range of normal when it comes to hCG levels in early pregnancy, and sometimes unusual numbers aren't a cause for concern. You can experience dropped hCG levels and not miscarry, anda healthy babymight still result from a pregnancy with...
2. The absorbance of this quantitative assay is to 50 mIU/ml of β-hCG. It is recommended that samples falling above the range should be diluted with sample diluent (Zero Buffer) to absorbance that within the standard curve range. Calculation of results Calculate the mean absorbance value (...
Intended Use The Atellica® IM Total hCG (ThCG) assay is for in vitro diagnostic use in the quantitative determination of human chorionic gonadotropin (hCG) in human serum or plasma (EDTA or lithium heparin) using the Atellica® CI Analyzer. The results obtained from hCG specimens are used...
P for the treatment of early ectopic pregnancy options provide quantitative indexes.%目的:探讨血清β-人绒毛膜促性腺激素(β-hCG)雌二醇(E2)和孕酮(P)测定对异位妊娠早期诊断,异位妊娠保守治疗方法选择及疗效的价值.方法:选择异位妊娠患者150例(A组),正常宫内早孕者100例(B组).采用化学发光法测定并比较两组...
The relationship between quantitative variables was evaluated using ANOVA test. P values less than 0.05 were considered as significant. Tukey test was used as a nonparametric equivalent for ANOVA for comparison of two or more subgroups within each group. This test was used for comparison of median...

1. ACCU-TELL®HCG Pregnancy Rapid Test Cassette/Strip (Serum/Plasma/Urine) is a preliminary qualitative test, herefore, neither the quantitative value nor the rate of increase in HCG can be determined by this test. 2. Very dilute urine specimens, as indicated by a low specific gravity, ...
pErk1/2 and pCreb semi-quantitative signals were normalized over total ERK and expressed in relative units. Data from gene expression analysis were represented as relative expression. All data were plotted as means ± standard error of mean (SEM). Mann-Whitney’s U-tests, two-way ANOVA ...
