Beckman Coulter B11754 Access Total Beta hCG Calibrator (S0-S5) for Total Beta hCG Test: INTENDED USE
The Access Total-Beta hCG (5th IS) Calibrators are intended to calibrate the Access Total-Beta hCG 5th IS assay for the quantitative determination of total-Beta hCG levels in human serum and plasma using the Access Immunoassay Systems.
Beckman Coulter B11754 Access Total Beta hCG Calibrator (S0-S5) for Total Beta hCG Test: SUMMARY AND EXPLANATION
Access Total Beta Quantitative assay calibration is the process by which samples with known analyte concentrations (i.e., assay calibrators) are tested to measure the response. The mathematical relationship between the measured responses and the known analyte concentrations establishes the calibration curve. This mathematical relationship, or calibration curve, is used to convert Relative Light Unit (RLU) measurements of samples of unknown concentration to specific quantitative analyte concentrations.
Clinical Significance
hCG, Total, Quantitative – hCG may reach detectable limits within 7-10 days of conception. hCG is produced by the placenta and reaches a peak between the 7th and 10th week of gestation. hCG is a glycoprotein hormone produced by the syncytiotrophoblast of the placenta and secreted during normal pregnancy and with pathologic conditions such as hydatidiform mole, choriocarcinoma and testicular neoplasm. Order hCG, Total, Qualitative, Urine, if hCG serum result is inconsistent with clinical presentation.

Immunoassay (IA)
What Is the Human Chorionic Gonadotropin (hCG) Blood Test?
Human chorionic gonadotropin (hCG) is produced during pregnancy. Your doctor may refer to the hCG blood test by another name, such as the:
- beta-hCG blood test
- quantitative blood pregnancy test
- quantitative hCG blood test
- repeat quantitative beta-hCG test
- quantitative serial beta-hCG test
There are important differences between hCG blood tests and the hCG urine tests that you can purchase over the counter.
Urine tests can be influenced by factors such as dehydration and the time of day that you test, while an hCG blood test can provide conclusive results even in cases where hCG levels are quite low.
What is human chorionic gonadotropin (hCG)?
During pregnancy, cells in the developing placenta make hCG. The placenta is the sac that nourishes the egg after it’s fertilized and attaches to the uterine wall.
hCG can first be detected in a blood sample about 11 days after conception. Levels of hCG continue to double every 48 to 72 hours. They reach their peak around 8 to 11 weeks after conception.
hCG levels then decline and level off, remaining steady for the rest of the pregnancy.
What do my hCG blood test results mean?
When your lab test comes back, your doctor will tell you what your hCG levels are. These levels are measured in milli-international units of hCG hormone per milliliter of blood (mIU/mL).
This table shows the normal hCG levels during pregnancy for each week from your last menstrual period, according to the Australian government’s pregnancy resource Pregnancy, Birth, and Baby.
| Weeks from last menstrual period | Normal hCG levels (mIU/mL) |
| 4 | 0–750 |
| 5 | 200–7,000 |
| 6 | 200–32,000 |
| 7 | 3,000–160,000 |
| 8–12 | 32,000–210,000 |
| 13–16 | 9,000–210,000 |
| 16–29 | 1,400–53,000 |
| 29–41 | 940–60,000 |
Normal hCG levels in nonpregnant women are less than 10.0 mIU/mL.
If your hCG levels are outside of the normal range, it could mean a variety of things. Your doctor will help you interpret the results.
Levels of hCG that are lower than normal could mean:
- a miscalculation of pregnancy dating
- a possible miscarriage or blighted ovum
- an ectopic pregnancy
Levels of hCG that are higher than normal could mean:
- a miscalculation of pregnancy dating
- a molar pregnancy, when an abnormal mass forms inside the uterus after fertilization instead of a normal embryo
- a multiple pregnancy, such as twins or triplets
