A false positive on a pregnancy test means that the test result says you are pregnant but you actually aren't. In most cases, this means the test detected thepregnancy hormone human chorionic gonadotropin (hCG)in your urine when there really was no hCG in your urine. Sometimes, however, th...
There are a couple of reasons you could seea faint line when reading your pregnancy testresults. If you’ve tested very early, the line may be faint since the concentration of hCG is still ramping up. You can also experience a faint line if you’re reading results past the dedicated windo...
While heterophile antibodies are common in IgA deficient serum, false positive assays for βhCG in IgA deficient serum have not been previously reported. The possibility of false positive test results should be considered prior to invasive procedures in IgA deficient patients....
The overall positive results were 6.1%, ranging from 5.6% among the hospitals near the laboratory to 15.4% among the hospitals far away from the laboratory (p-value < 0.001). The samples from the remote hospitals had significantly higher levels of free beta hCG than those from nearby ...

作者: M. Shepard 展开 摘要: Choriocarcinoma is a rare but curable malignancy. Diagnosis depends on serum human chorionic gonadotropin (hCG) levels. Occasionally, elevated serum hCG levels can persist when a woman does not have choriocarcinoma, putting such women at risk for needless treatment.Th...
In a pregnancy test, human chorionic gonadotropin (hCG), a hormone that rises when you’re pregnant, is measured and even a faint line is a positive result. An ovulation test measures the level of luteinizing hormone (LH). An ovulation test could show a faint line but that may not mean...

The results showed that MSAFP levels (3.14±2.80 ng/ml) were significantly lower (P < .05) in HIV infected pregnant women when compared to HIV uninfected pregnant women (4.75±3.68 ng/ml). There was no significant difference in the levels of β-hCG (217.88±63.85mIU/mL) in the test ...
These results confirm the efficacy of maternal serum screening for fetal chromosomal abnormalities with a low FPR. The measurement of AFP, b-hCG and uE3 is an effective prenatal screening test. 展开 关键词: Prenatal diagnosis fetal chromosomal abnormalities maternal serum screening alpha-fetoprotein ...
