Difference Between Beta hCG and hCG

Is there a difference between hCG and beta hCG?

If the test is negative, it is often repeated several days later. Since hCG rises rapidly, an initial negative test can turn positive within this time period. Quantitative hCG testing, often called beta hCG (β-hCG), measures the amount of hCG present in the blood.

What is a positive beta hCG test?

A positive beta hCG levels means that you are pregnant. The hCG level depends on how far along a woman is in her pregnancy. A positive beta human chorionic gonadotropin (hCG) level usually means that you are pregnant. Pregnancy tests detect the hCG hormone in the blood and urine.

What is the Beta hCG level for pregnancy?

An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for pregnancy. An hCG level between 6 and 24 mIU/mL is considered a grey area, and you'll likely need to be retested to see if your levels rise to confirm a pregnancy.

Can beta hCG detect early pregnancy?

However, the pregnancy hormone can be detected as early as 8 days after conception, and the level increases rapidly during the early stages of pregnancy. Usually, healthcare professionals conduct qualitative hCG blood tests, so results typically take longer than a home pregnancy test.

Do Boy pregnancies produce less hCG?

Hormone differences for baby boys and girls

Studies have shown hCG (human chorionic gonadotropin, the hormone responsible for the second line appearing on a home pregnancy test) is higher for female fetuses compared with males, and remains higher throughout pregnancy.

What is the hCG level at 1 week?

The placenta starts to produce HCG once the sperm fertilises the egg, therefore it usually takes around two weeks for the levels to be high enough to be detected by a pregnancy test. Average hCG levels: Less than 10 U/L in non-pregnant women. 10 to 25 U/L for a 'borderline' pregnancy result.

What is borderline pregnancy?

A borderline result is generated by some assays when the hCG level is between 5 and 25 mIU/mL. Samples reported as borderline are considered indeterminate, and clinicians should request a repeat test within 48 to 72 hours or obtain a quantitative serum hCG.

What is the hCG level of a nonpregnant woman?

Normal hCG levels in nonpregnant women are less than 10.0 mIU/mL.

How can I check my hCG levels at home?

For some home pregnancy tests, you'll hold an indicator stick directly in your urine stream until it's soaked, which should take about 5 seconds. Other kits require that you collect urine in a cup and then dip the indicator stick into the cup to measure the hCG hormone level.

When does your body start producing hCG?

A woman's body begins to produce hCG from cells in the developing placenta (tissue that nourishes a growing fetus) soon after implantation of a fertilized egg inside the uterus. Around eight days after ovulation, trace levels of hCG can be detected from an early pregnancy.

Can hCG blood test tell how far along you are?

The two main types of blood pregnancy test include: Quantitative blood test – measures the exact amount of hCG in the blood and can give you an estimate of how far along the pregnancy has progressed.

Can I be 5 weeks pregnant and still test negative?

Although it's less likely, it is still possible to be pregnant even if urine and blood tests come back negative. If you still believe you are pregnant after receiving negative urine and blood test results, your medical provider can perform a transvaginal ultrasound to determine whether you are pregnant.
