SelectedThe Pregnancy Test – Beta hCG is a blood test that measures beta human chorionic gonadotropin (hCG), a hormone produced shortly after a fertilised egg implants in the uterus. hCG is essential for maintaining early pregnancy.
Unlike urine pregnancy tests, blood testing can detect very low levels of hCG and provides a precise measurement rather than a simple positive or negative result. This makes it particularly useful in early pregnancy assessment.
The Beta hCG test is commonly used to confirm pregnancy, assess early pregnancy progression, and support investigation of pregnancy-related concerns.
The Beta hCG blood test is useful when pregnancy needs to be confirmed accurately or monitored closely. It can detect pregnancy earlier than urine tests and provides quantitative results that help guide clinical interpretation.
This test is also important in situations where pregnancy symptoms are unclear, cycles are irregular, or there are concerns about early pregnancy development.
You may benefit from this test if you:
Suspect early pregnancy
Have irregular menstrual cycles
Need confirmation beyond a urine test
Are monitoring early pregnancy progression
Have abdominal pain or spotting
Are undergoing fertility treatment
Need pregnancy exclusion before medical procedures
Require medical confirmation of pregnancy

Low or undetectable hCG suggests no current pregnancy or testing performed very early. Repeat testing may be considered if pregnancy is still suspected.
UK reference interpretation:
Not pregnant: <5 IU/L
Detectable and rising hCG levels indicate early pregnancy. Values typically increase rapidly in the first weeks following implantation.
UK reference interpretation:
Early pregnancy: ≥5 IU/L
Higher hCG levels may reflect later gestation, multiple pregnancy, or individual variation. Results should always be interpreted in clinical context.
UK reference interpretation:
Elevated: Above expected range for gestation

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
