What is the Pregnancy Blood Test?
Human chorionic gonadotropin is a glycoprotein hormone consisting of two α and β subunits naturally produced by the placenta. HCG determination is useful for confirming pregnancy and evaluating trophoblastic tumours. Its role is to maintain the corpus luteum during pregnancy. And its concentration increases exponentially during pregnancy, reaching the maximum value in weeks 8-11.
Why get a Pregnancy Blood test?

Beta-HCG
Scientific Information Data from Instrument and Reagent Supplier
Testing Technology Method:
Fluorescence quantitative immunoassay
Limit of Detection:
5.0 mIU/mL
Precision:
The within-assay CV is less than or equal to 10%. The between-assay CV is less than or equal to 15%.
Measuring Range:
Validation-Active Information:
- EQA: Yes
- Inter-laboratory validations
- Periodic according to validation schedule
- Event-triggered- Qc/Calibration/New materials/Batch
Test Precision:
The precision relies on the within-assay coefficient of variations and the between-assay coefficient. The within-assay coefficient of variations is the variance of the result value if the same test was analysed again. The between assay coefficient is the variance of the result value if the same sample was reprocessed from the beginning again.
In range results:
Beta-HCG: <5.0 mIU/mL
Normal pregnancy:
- 0.2 – 1 gestational weeks: 5-50 mIU/mL
- 1-2 weeks: 50-500 mIU/mL
- 2-3 weeks: 100-5000 mIU/mL
- 3-4 weeks: 500-10,000 mIU/mL
- 4-5 weeks: 1,000-50,000 mIU/mL
- 5-6 weeks: 10,000-100,000 mIU/mL
- 6-8 weeks: 15,000-200,000 mIU/mL
Out-of-range results:
Beta-HCG levels ≥ 25.0 mIU/mL are considered positive.
