hCG is a polypeptide hormone produced by the human trophoblast in the developing embryo. It is composed of alpha and beta subunits. The alpha subunit is essentially identical to the alpha subunits of human pituitary gonadotropins: luteinizing hormone (LH), follicle stimulating hormone (FSH), and thyroid stimulating hormone (TSH). The beta subunits of these hormones differ in their amino acid sequences. As far as its action is concerned, hCG is virtually identical to the pituitary hormone LH.

Intramuscular injection is generally recommended for hCG. However, a new recombinant form of hCG is available, Ovidrel, which is designed for subcutaneous administration.

The hormone beta hCG is produced by the placenta. In normal pregnancy the levels double every two days. When the level in urine is high enough, the home pregnancy test becomes positive. In ectopic pregnancy, the levels are usually lower and rise more slowly (and your pregnancy may not test positive). A combination of ultrasound findings and blood levels of hCG can make a more accurate and earlier diagnosis allowing more treatment options.

Lola, Utah, USA: Testing of hCG levels in the blood is done frequently for GTD. Some physicians will suggest weekly blood testing at first, to confirm regression of the trophoblastic tumor. After remission is achieved, hCG levels are monitored closely, generally with a weekly test for the first month, bi-weekly testing for the second and third months, and then every three months.

An rounded-off average would be about 25 mIU at 10 dpo, 50 at 12 dpo, 100 at 14 dpo. Please consult for charts on hCG levels in early pregnancy. You may be pregnant and just didn't have a high enough level of hCG to trigger the test within the usual time frame; however, it also could be the way that test reacts over time, so you really need to test again either way in order to be sure of the result. Some brands indicate that an "evaporation line" will appear if the test is left to sit.

In all cases of molar pregnancy and the other forms of trophoblast disease the hCG level is important for making the diagnosis and for monitoring treatment. The abbreviation hCG is short for human Chorionic Gonadotrophin, the pregnancy test hormone that is detected in home pregnancy tests. In pregnancy (normal and molar) when the egg is fertilised it starts to make hCG and then as the pregnancy develops the trophoblast/placental cells take over making hCG.

The HCG injection can stay in your body for approx 10-14 days but obviously we all eliminate the drugs from our systems at different rates. As a very basic approximation, 1000iu of pregnyl eliminated from body per day so gives you a rough idea.

Lola, Utah, USA: Yes, some elevated hCG levels can be due to other factors besides GTD or recurrent trophoblastic disease. Certain hormone fluctuations and proteins in the blood may interfere with blood test results. Both tests should be requested, especially in initial diagnosis of GTD, as well as diagnostic testing for suspected GTD, before any invasive treatment recommendations are pursued. Lola, Utah, USA: GTD is diagnosed and followed by measuring hCG hormone in the blood and urine.

The lower the number of units of hCG in your urine detected means that you will be able to test earlier. The test is more sensitive, and more likely to pick up an early pregnancy, 10-14 dpo. (days past ovulation)

You can, but you should wait 7-14 days after your last injection before the shot is out of your system. If you test too soon, you might get a false positive. Ask your OB/RE when you should test.

HCG is an abbreviation for Humane Chorido Gonadotrophine. This is a hormone that exists in the urine of pregnant women.

No, since our HCG is used in a strongly dilute solution, it cannot harm your health. During the first two days of the treatment you may have some headache, that is caused by the changing dietary pattern.

You will always receive 6000 u.i. HCG, enough for 23 days. You will receive 6 ampoules of 1000 u.i. or 4 ampoules of 1500 u.i. depending on what we have in stock. You will receive more than enough HCG for 23 days. All treatments include enough syringes and needles for the HCG, as well as instructions and diet suggestions.

Most hCG dieters report a loss of 1 to 2 lbs a day. At the very least, .5 pound a day, and at the most, 3 lbs a day. 1 lb is generally lost in the first day. Factors that guarantee faster weight loss include adding/increasing vegetable intake and mixing salad with each meal. Fiber intake is extremely important, as is water intake.
