After taking a look at the conversation, we understood that the best pregnancy tests are easy to use, offer clear results, and are a good value for the money. We found the tests that met this standard, and compared them against criteria from expert organizations like The American College of Obstetricians and Gynecologists and the Food and Drug Administration, as well as recommendations from experts like Dr. Tarun Jain. There are two common types of hCG tests. A qualitative test detects if hCG is present in the blood. A quantitative test (or beta) measures the amount of hCG actually present in the blood.

hCG levels: all you need to know - Clearblue

HCG ( Human Chorionic Gonadotropin) is often called the pregnancy hormone because it is made by cells formed in the placenta, which nourishes the egg after it has been fertilized and becomes attached to the uterine wall. Levels can first be detected by a blood test about 11 days after conception and about 12-14 days after conception by a urine test.If you’re testing on the first day of a missed period, it doesn’t matter very much which test you use—most currently marketed tests are reliable and will yield a positive result for 98 percent of pregnant women. But if you’re testing earlier than your missed period, you should use a more sensitive test.

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. At about 4 weeks pregnant, the egg—now called an embryo—implants further into the uterus and begins to produce even more hCG, which triggers increased productions of other hormones like oestrogen and progesterone. This daily increase in urinary hCG levels by approximately 50% observed in early pregnancy was consistently noted in different studies conducted across a 5-year period, using three different cohorts of women, as shown in Fig.1. All of the studies reported a remarkable uniformity in the rise of hCG levels in early pregnancy. This combined cohort data has been used to provide reference ranges for hCG for each day of pregnancy ( Table 2). The studies reported no differences between ethnicities with regard to urinary hCGA transvaginal ultrasound should be able to show at least a gestational sac once the hCG levels have reached between 1,000 – 2,000 mIU/mL. Because levels can differentiate so much and conception dating can be wrong, a diagnosis should not be made by ultrasound findings until the hCG level has reached at least 2,000 mIU/mL.

During those first few weeks of pregnancy, you may not show any outward signs of being pregnant and may not even know you’re pregnant yet! However, you may experience some implantation bleeding when the fertilized egg attaches to the lining of the uterus (as described above). Implantation bleeding is totally normal and often comes in the form of light spotting. When Can Pregnancy Tests Detect hCG? The investigation of claims made about pregnancy tests in Germany found that some made claims consistent with the clinical rise in hCG in early pregnancy. For example, tests claiming 25mIU/ml sensitivity were declared to be >99% accurate from the day of the expected period and capable of detecting pregnancy up to 4 days before the expected period. These tests are likely to be correct, providing the test is always able to detect 25mIU/ml of hCG in every urine sample. However, other tests are making claims such as “8 days early”, or “can detect 10mIU/ml”; these claimsFrom what I’ve read they are almost as sensitive as FRER [First Response] which makes me feel less guilty a little burning through them as cheap as they are." The final variable is hCG doubling time. While hCG levels double on average every 48 hours, this figure can vary from woman to woman. If your hCG doubling time is on the slower side, it will take a little longer until you have enough hCG in your body to get a positive pregnancy test. Based on all three of these variables, you can see that it’s highly unlikely to get a positive pregnancy test before 9 – 10 DPO (days after ovulation), and most women probably won’t test positive until 11 – 12 days after ovulation.

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.
