For good measure, what is the earliest hCG can be detected?
hCG can be detected in urine or blood after implantation, which occurs on average, about 9 days (range 6-12 days) after fertilization. Some home pregnancy tests claim to detect hCG as early as 4 days before the next expected period yet that claim depends on your luteal phase and how soon the embryo implanted.
Beyond, is it possible to have a positive pregnancy test at 3 weeks? It's too early to take a home pregnancy test in week 3. But, by the middle or later part of next week, you might be able to detect the pregnancy hormone hCG in your urine with a sensitive early test.
Anyhow, how much hCG does clearblue detect?
Based on these studies, hCG threshold data for a few common pregnancy test brands are available: Clearblue (manual and digital tests): 22 mIU/ml. e.p.t. (manual and digital tests): 22 mIU/ml. First Response Early Results: 6.3 mIU/ml.
What does 3+ weeks mean on clearblue?
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.
