How do I read my hCG lab results?

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.

How is hCG ratio calculated?

The HCG ratio is calculated by dividing the serum HCG concentration of one sample by that taken 48 hours earlier. Ratios greater than 1.66 generally indicate viable early pregnancies. Earlier work advocated the use of the HCG doubling time, which requires an accurate estimation of the time interval between samples.

What hCG level is heartbeat visible?

Every patient with an HCG level greater than 10,800 mIU/ml had a visible embryo with a heartbeat.

What level of hCG indicates miscarriage?

When you miscarry (and also anytime you give birth), your body no longer produces hCG. Your levels will ultimately go back to 0 mIU/mL. In fact, anything less than 5 mIU/mL is “negative,” so effectively, 1 to 4 mIU/mL is also considered “zero” by doctors.

How do you calculate hCG?

To calculate your hCG levels, you will have to enter the data from two beta hCG samples. The hcg levels calculator will check the doubling time between the two levels. You have to first enter the value of your first hCG test levels. Then enter value of the second hCG test levels. Mention the time gap between the two hCG tests.

What is the normal hCG level for 8 weeks?

Normal hCG levels after week eight range from 7,650 to 229,000 mIU/ml, the American Pregnancy Association reports. Levels will remain static and then slowly rise after week 22 until delivery, according to Neinstein.

How much should hCG levels rise daily?

The hCG doubles every 48-72 hours and it should increase normally by at least 60% every 2 days. Between 1,200 and 6,000 mIU/ml. The hCG takes 72-96 hours to increase and double. Levels above 6,000mIU/ml.

What causes elevated hCG levels?

Interfering antibodies, hormonal changes, using hormone replacement therapy (HRT), and lab errors may all cause you to have a positive hCG test. Smoking tobacco and using marijuana can increase hCG levels, too.
