When the pregnancy Test is positive?

To become a positive pregnancy test, the fertilized egg to implant in the uterus first and then send sufficient amounts of pregnancy hormone hCG in your blood stream for enough hCG create a positive pregnancy test.

The installation, when the fertilized egg implants in endometrium, happens approximately one week after ovulation (range: 6-12 days), and takes another 3-4 days after planting (9-10 dpo: days after ovulation) for blood pregnancy tests before becoming positive.

blood pregnancy tests: If you are pregnant then the blood pregnancy tests is generally positive within 3-4 days after implantation, or about 9-10 days after fertilisation and ovulation.
Urine pregnancy Test (Home HPT): The pregnancy tests of urine usually does not become positive in the majority of women up to a period, or about a week after implantation. Many manufacturers of urine pregnancy test you want to believe that the urine is usually positive before a period of failure, but only about 25% of pregnant women will test positive with the HPT 2 days before your missed period and about 40% the day before the time of failure. The wide variation when the urine pregnancy test is positive due to four variables that determine when the pregnancy test positive urine becomes:

Timing of blood facility hCG Urine hCG levels level (eg. how concentrated or dilute urine is) pregnancy test sensitivity
1. planting Times

A pregnancy test detects the presence of the pregnancy hormone hCG (human chorionic gonadotropin) in the blood or urine. HCG in urine hCG blood comes in after it has been filtered through the kidney. After ovulation, the egg fertilized Gets and travels through the fallopian tube toward the uterus. This trip lasts on average about one week. The plant, the attachment of the fertilized egg in the uterine lining, occurs on average about a week or so later, after ovulation/fertilization, but can happen as soon as six days and not later than 12 days after fertilization/ovulation. At the time of installation, the placenta begins by the pregnancy hormone hCG, then enters the blood stream. hCG can be detected in the blood for about three or four days after implantation. Urine hCG can be detected approximately two or three days after hCG the blood before it can be seen. Detection of hCG is dependent on the timing of the plant, so normally hCG can be detected in blood between nine and 16 days after ovulation (HPT: 12-19 days after ovulation).

2. blood hCG level

There is a wide variation of normal levels of hCG in urine and blood. If a woman has low levels of hCG blood, for example, then it may take several days to show on a pregnancy test.

3. Urine hCG level

Change of levels of hCG Urine during the day depending on how much you drink and as a diluted or concentrated urine is urine pregnancy Test is done best with the urine more concentrated. If you drink a lot of fluid, urine diluted may be too early in pregnancy to reach a concentration of hCG quite adequate for a positive test.

4. sensitivity urine pregnancy tests Home

Various pregnancy tests have different sensitivity. The lower the sensitivity, the previous a pregnancy test is positive. Sensitivity are mIU/mL, the minimum amount of hCG in urine which tests positive. A sensitivity of 20 mIU/mL requires half the level of hCG positive when compared with a sensitivity level 40 mIU/mL, and can become positive for several days prior to the pregnancy test with a sensitivity higher. Make sure you read the package of the pregnancy test to determine the sensitivity of the pregnancy test.
