The samples were divided, and serial hCG standard dilutions were spiked with a 1:10 dilution factor: one part standard to nine parts negative pool. The whole blood and serum samples were thus spiked to the following hCG concentrations: 1,860 IU/L, 930 IU/L, 465 IU/L, 232.5 ...
Qualitative: These hCG tests give a positive or negative result depending on the presence or absence of hCG in the sample. Qualitative tests can be done using either a blood or urine sample. This type of testing is done most often to confirm a pregnancy. Quantitative: This type of hCG test...
Two types of beta hCG testing are usually used Qualitative testing:Also known as the urine pregnancy test, the qualitative beta hCG test is theover-the-counterpregnancy test that only indicates whether you are pregnant. Quantitative testing:It measures the amount of the hormone present in the blo...
The patient had developed vaginal bleeding, and her laboratory testing was characterized by elevated serum human chorionic gonadotropin (β-hCG) concentrations, but negative qualitative urine results. After a thorough gynecological evaluation to exclude unexpected normal, ectopic, or molar pregnancy, we ...

The hCG colloidal gold immunochromatographic assay is a qualitative test and cannot be used to determine the concentration of hCG in a specimen. The test may not detect all cases of pregnancy.A negative result does not rule out pregnancy. If pregnancy is suspected, a quantitative hCG blood test...

All serum β-hCG levels were evaluated at our hospital laboratory using electrochemiluminescence immunoassay (Roche Labs). Δβ-hCG increment was calculated as the ratio of the second β-hCG divided by the first. We evaluated the collinearity between the two measurements to rule out any ...
and the rate of the negative samples was 96.4%.There was no significant difference between the results measured by two methods(P0.05).The results indicated that GICA may be a simple and effective method in fast quantitative determination of β-HCG and possesses a fixed clinical application value...
