Human Chorionic Gonadotropin (hCG) ELISA Kit

  • Created on the 15 February, 2017.

BACKGROUND

Chorionic gonadotropin (hCG) is a 38.4 kD glycoprotein hormone that is usually secreted by the placenta during pregnancy. Structurally it is composed of two subunits, alpha and beta, where the alpha subunit is identical to that found in FSH, TSH and LH glycoprotein hormones and the beta subunit is the specific portion and this in known to differ from one hormone to another. The difference in the beta subunit accounts for the immunochemical distinctiveness and the biological specificity of each hormone.

After conception, the concentration of hCG is rapidly elevated until it reaches a peak towards the end of the first trimester. This high concentration is then maintained throughout pregnancy. After delivery, the concentration of hCG falls rapidly and returns to undetectable levels a few days later after. In non-pregnant women or men an increased level of hCG indicates neoplasia. The determination of hCG concentrations has been helpful in monitoring and recognising chorionic tumors or malignancies (such as; pancreatic, testicular and bronchogenic pulmonary cancers).

INTENDED USE

hCG ELISA kit is a reliable quantitative procedure for measuring human chorionic gonadotropin (hCG) in serum and plasma. This assay has a minimum sensitivity detection limit of < 5.0 mIU/ml.

SENSITIVITY

The minimum sensitivity detection limit of chorionic gonadotropin using this hCG ELISA kit was approximately 5.0 mIU/ml. The dynamic assay range for this kit is 5.0 – 1,000.0 mIU/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
