The Clearblue Ultra Early Pregnancy Test (also called Early Digital) is Clearblue's most sensitive test, designed to detect pregnancy up to 6 days before your missed period, identifying lower levels of the hCG hormone earlier than other tests. While it's highly sensitive for early testing, it's still crucial to test on or closer to your expected period day for the most accurate results, as sensitivity increases as hCG levels rise, say Clearblue.
The Clearblue® Early Detection Pregnancy Test is a highly sensitive pregnancy test (10 mIU/mL), allowing women to test as early as 6 days before the missed period, which is 5 days before the day of the expected period.
She's not kidding—First Response Early Results is the most sensitive pregnancy test that we tried. Studies show that it can pick up hCG levels as low as 6.3 mlU/mL in 50 percent of cases, while comparable early testing products have a higher 10 mlU/mL sensitivity.
First Response appears to be a more sensitive test than ClearBlue meaning it can detect pregnancy sooner.
Understanding Your Result
1–2 weeks since conception (approximately 3–4 weeks pregnant). 2–3 weeks since conception (approximately 4–5 weeks pregnant). 3+ weeks since conception (5+ weeks pregnant).
For example, women who have chronic health problems, such as high blood pressure or diabetes, who become pregnant may be considered to have high-risk pregnancies—even if the condition is well controlled. Other factors, such as infections, injuries, and disorders of pregnancy, can also put a pregnancy at high risk.
While traditional pregnancy tests often claim to detect hCG at a level of 25 mIU/ml, a digital pregnancy test, like Clearblue Early Digital Pregnancy Test, can detect hCG at 10 mlU/ml.
If there are enough levels of hCG in your urine, the at-home pregnancy test will read as positive. While stress can affect your hormone levels and even delay your ovulation or period, it does not affect pregnancy test results.
Therefore, we suggest that in the overall mechanism regulating HCG secretion, under stressful situations, when these hormone levels decrease they may consequently cause a lowered HCG release, thus impairing early pregnancy development.
Generally, most home pregnancy tests claim to detect hCG levels from 25 mIU/ml. However, some tests, such as the Clearblue® Early Digital Pregnancy Test and the Clearblue® Early Detection Pregnancy Test, are so sensitive they can detect hCG levels as low as 10 mIU/ml.
hCG is present in the body shortly after implantation, and its levels increase rapidly during the first few weeks of pregnancy. HCG levels rise dramatically in healthy pregnancies, doubling every 48 to 72 hours. This rapid increase makes hCG a reliable marker for confirming and monitoring early pregnancy.
The first morning urine is the urine you void when you get up for the day. If you get up during the night, it is not necessary to catch that urine. You can wait until you get up for the day.
78% of pregnancies can be detected 6 days before your missed period, 93% of pregnancies 5 days before and 99% or more from 4 days before your missed period. Digital 'Pregnant' or 'Not Pregnant' result in words for more trust in your early result.
The Clearblue® Digital Ovulation Test has been shown in extensive laboratory trials to be over 99% accurate in detecting the LH surge prior to ovulation. The sensitivity of the Clearblue® Digital Ovulation Test is 40mIU/ml.
No, folic acid does not directly increase hCG (human chorionic gonadotropin) levels. HCG is a hormone produced during pregnancy, and its levels are influenced by the presence of the developing embryo. Folic acid, while crucial for fetal development, does not impact hCG production.
When you can do a pregnancy test. You can carry out most pregnancy tests from the first day of a missed period. If you don't know when your next period is due, do the test at least 21 days after you last had unprotected sex. Some very sensitive pregnancy tests can be used even before you miss a period.
If the test is expired, taken too early in the day, or if your urine is too diluted, the result may not be accurate. Even something as simple as not following the instructions carefully can affect the outcome. So if you're getting a negative result but still feel pregnant, it's not necessarily all in your head.
If the test result is 'Pregnant' a numerical result: "1-2", "2-3" or "3+", is also displayed indicating that conception occurred 1 to 2 weeks ago, 2 to 3 weeks ago or 3 or more weeks ago.
EarlyPT™ is one of the most sensitive at-home early pregnancy tests available today. Our early detection pregnancy test is clinically proven to provide accurate results up to 6 days before your missed period. Plus it's easy to use and provides clear results in just 5 minutes.
Normal HCG Levels at 4 Weeks Pregnant
Typical levels of HCG at 4 weeks can be anywhere from 5 to 426 mIU/mL. A value within this range—and even slightly outside of it—can still result in a perfectly healthy pregnancy. If your HCG is on the lower side, it may simply mean you implanted a bit later.
Most miscarriages happen in the first 12 weeks of pregnancy (known as early miscarriage). It is estimated that early miscarriages happen to 10-20 in 100 (10 to 20%) of pregnancies. It is estimated that second trimester loss (late miscarriage) happens to 3-4 in 100 (3 to 4%) of pregnancies.
