Pregnancy Testing at the Doctorâs Office Quantitative hCG testing, often called beta hCG (β-hCG), measures the amount of hCG present in the blood. It may be used to confirm a pregnancy. It may also be used, along with a progesterone test, to help diagnose an ectopic pregnancy, to help diagnose and monitor a pregnancy that may be failing, and/or to monitor a woman after a miscarriage.

- The FIRST RESPONSE™ Early Result In-Stream Pregnancy Test is sensitive enough that most women have enough hCG to be detected as early as 6 days sooner than the day of their missed period (5 days before day of expected period).

IVF Cycle Details Fertilization & ICSI. Sperm Collection: Day of Egg Retrieval. Sperm are obtained from the male partner on the day of egg retrieval, typically about 12:00 noon. In about 50 percent of cases, an additional specimen is obtained 48 hours prior to follicle aspiration, on the day of HCG.

HCG, TOTAL (U) QL - Beta hCG Quantitative (pregnancy test) values may reach detectable limits within 7-10 days of conception. hCG is produced by the placenta and reaches a peak between the 7th and 10th week of gestation. hCG is a glycoprotein hormone which is secreted during normal pregnancy and with pathologic conditions such as hydatidiform mole, choriocarcinoma and testicular neoplasm. If the hCG serum result is inconsistent with clinical presentation, then ordering hCG, Total, Qualitative, Urine is recommended.

- Question 2. The serum hCG test can be positive as early as 7-10 days following conception. However, in some pregnant women, the test is not positive 7-10 days after conception. This is because the time to implantation (and production of hCG) can be longer in some women.

Urine hCG Level Test What Is an hCG Urine Test? A human chorionic gonadotropin (hCG) urine test is a pregnancy test. A pregnant woman’s placenta produces hCG, also called the pregnancy hormone. If you’re pregnant, the test can usually detect this hormone in your urine about 10 days after your first missed period. This is when the fertilized egg attaches to the uterine wall.

- The amount of hCG produced and secreted by the trophoblast layer increases, until it reaches a peak at about 8 weeks of pregnancy (120 to 130 IU/ml). It then decreases in amount, reaching a low at about 16 weeks (20-30 IU/ml), and remaining there for the rest of the pregnancy.etection of hCG is the basis of both laboratory and home pregnancy tests. The presence of hCG can be detected in the maternal serum 24-48 hours after implantation. It can be found in the maternal urine just a few days later.

- The Timing. While HCG may be present in a woman's urine as early as 10 days after fertilization, which can also be 2 or 3 days before missing her period, there is a high incidence of false positives when taken this early. This means the test may read that a woman is pregnant when she is not.

- Qualitative hCG testing detects the presence of hCG and is routinely used to screen for a pregnancy. This test may be performed by a laboratory, at a doctor's office, or at home using a home pregnancy test kit.he blood level of hcG in a woman with an ectopic pregnancy usually rises at a slower rate than normal. Typically, hCG levels double about every two days for the first four weeks of a normal pregnancy, then slow to every 31/2 days by six weeks.

- Serial hCG Blood Tests. Serial hCG blood tests are two quantitative hCG blood tests done two to three days apart. In early pregnancy, the hCG level usually doubles roughly every two to three days. If the hCG doubling time is slower or if the level decreases over time, this is a possible sign of miscarriage or ectopic pregnancy.

How soon can you do pg pee test after HCG trigger? Every woman's metabolism is different, but as a general rule of thumb, you should allow 1 day for every 1,000 units of hCG you injected. The standard hCG dose is 10,000 units; thus, 10 days after the shot, the synthetic hCG should be gone and you should be able to test for pregnancy without detecting the shot. However, you should ask your doctor what the recommended protocol for your dosage is..

Getting pregnant Take the test too early. The earlier after a missed period that you take a home pregnancy test, the harder it is for the test to detect HCG. For the most accurate results, take the test one week after a missed period — when the level of HCG in your urine is most likely to be detectable. If you can't wait that long, ask your health care provider for a blood test. Check test results too soon. Be sure to give the test time to work.

SUCCESS RATES never mattered more 85% of normal pregnancies will have the HCG level double every 72 hours. HCG levels peak at about 8-10 weeks of pregnancy and then decline, remaining at lower levels for the rest of the pregnancy. There is a large variation in a normal HCG level for any given time in pregnancy.

When Can I Take A Pregnancy Test with hCG Shot?Last updated on Jan 12, 2013by Dr. Renee Hanton, MD So, how long? Trace amounts of hCG can remain the body for as many as fourteen days after hCG injections. The rule of thumb that doctors use is that it takes one day for each 1000 units of hCG to leave your boy. So, if you get a 10,000 unit injection of hCG, it will take approximately ten days for it to all leave your system. Most doctors will err on the longer side of the time frame to ensure that you get an accurate result.

hCG Level and Early PregnancyLast updated on Oct 24, 2012by Lindsey Zaldivar If you are taking a urine pregnancy test, hCG levels can be detected as early as twelve to fourteen days after conception. Around every 72 hours or so, hCG levels in a pregnant woman should double. hCG levels peak at around eight to twelve weeks, and after that they will start to level off for the rest of a pregnancy.

- A. Urine specimens should be collected in a clean, dry container such as a urine collection cup. B. Specimens may be collected at any time of the day. First morning urine samples will normally contain the highest levels of hCG. C. If not tested immediately, urine may be stored at refrigerated at 36─46oF (2─8oC) for up to 48 hours. Samples must be brought to room temperature before testing. D.

Why Are hCG Doubling Times Important in Early Pregnancy? The conventional wisdom is that in early pregnancy, the level of hCG in a quantitative hCG blood test should double about every two to three days -- but if yours is rising slower, don't panic quite yet. The numbers are just a guideline and the change in the level may be more important than the actual number.
