Beckman Coulter A85264 Access Total BHCG, Beta HCG test (BHCG Test): INTENDED USE

The Access Total hCG (5th IS) assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of total hCG levels in human serum and plasma using the Access Immunoassay Systems. This assay is intended for use as an aid in the early detection of pregnancy.

Beckman Coulter A85264 Access Total BHCG, Beta HCG test (BHCG Test): SUMMARY AND EXPLANATION

Human chorionic gonadotropin (hCG) is a glycoprotein hormone, produced by the placenta, with structural similarity to the pituitary hormones FSH, TSH, and LH. The alpha subunits (MW 15,000-20,000 daltons) are common to all of these hormones but the beta subunits differ, and confer immunological and biological specificity. hCG (MW 25,000-30,000 daltons) shares several peptide sequences with ?LH, but has a unique carboxyl terminal region.Shortly after implantation of a fertilized ovum into the uterine wall, the trophoblast begins to produce hCG, which maintains steroid secretions of the corpus luteum until the placenta can do so. hCG can be detected after implantation; concentrations double approximately every 1.5 to 3 days for the first six weeks and then continue to rise until the end of the first trimester, gradually falling to a lower level for the remainder of the pregnancy. After delivery, hCG returns to < 5 mIU/mL (IU/L) and is usually undetectable several days postpartum.The hormone is an excellent marker for pregnancy. Healthy, non-pregnant individuals have low (< 5 mIU/mL [IU/L]) to undetectable hCG levels; however, hCG, originating from the pituitary gland, can be found at detectable levels in periand post-menopausal women. During pregnancy, unusually low or rapidly declining levels may indicate an abnormal condition such as an ectopic pregnancy or impending spontaneous abortion.

Beta human chorionic gonadotropin (HCG) is a hormone produced by the placenta during pregnancy, and is typically detected in the blood. A beta HCG test is a blood test used to diagnose pregnancy, and usually becomes positive around the time of the first missed period.

How is a Beta HCG test (BHCG Test) performed?

Beta HCG test (BHCG Test) requires a small tube of blood, taken from a vein by your doctor.

Beta HCG test (BHCG Test or blood pregnancy test) may be performed by your doctor if they suspect that you may be pregnant, or if you suspect pregnancy yourself! Usual pregnancy symptoms include a missed or late period (amenorrhea), breast fullness or tenderness, or nausea and vomiting (morning sickness).

The test is often routinely performed in women of childbearing age with abdominal pain, and those who require an Abdominal X-Ray or Pelvic X-Ray, because of concerns or radiation to an unborn baby.

In some situations a quantitative beta HCG may be useful. This measures the amount of this hormone in the blood. Under normal circumstances, this level doubles approximately every 2 days, in the first trimester.

Beta HCG test (BHCG Test) results explained

Qualitative beta HCG:

  • A POSITIVE beta HCG means that the woman IS pregnant
  • A NEGATIVE beta HCG means that the woman is NOT pregnant

Quantitative beta HCG:

  • The result is given as a number, indicating the measured concentration of the hormone in the blood
  • The fetus is usually visible on a trans-vaginal ultrasound scan when the level is above 1500 units
  • When the level is above 4000 units, the fetus is also usually visible on a transabdominal ultrasound scan
  • The beta HCG level usually doubles approximately every 2 days
