What does it mean to have a chorionic gonadotropin assay?

Pregnancy test. Hcg is the hormone made by the placenta that is measured in a pregnancy test. It is tested to diagnose pregnancy, perform a risk assessment for ectopic pregnancy, and to manage certain complications of pregnancy, including a molar pregnancy.
HCG assay. Hcg is the hormone produced by the placental cells, and its level can be measured to diagnose or monitor a pregnancy. Hcg can be detected by commercial blood test as early as 5 days after implantation, or 7-10 days using the urine test. Because hcg's structure is similar to lh's, it can also be used to induce ovulation. After an HCG injection, the medication is completely elimnated after a week.

What are the side effects of chorionic gonadotropin?

HCG side effects. Hcg will cause bloating, sore ovaries, and pregnancy symptoms. It causes ovulation in 36-44 hrs after the injection and supports the luteal phase.

Is human chorionic gonadotropin only produced if pregnant?

Pretty Much. Hcg is also produced by molar pregnancies and choriocarcinoma, a type of cancer that is similar to pregnancy tissue. Outside of these, its just pregnancy.

How can antibodies be used to detect human chorionic gonadotropin?

Immunoassay. A technique known as the immunoassay, first developed by Berson and Yalow in the late '50's and early '60's, and for which they won the Nobel prize in 1977, uses hCG-specific antibodies to quantifiably identify the hCG, then a secondary antibody with a quantifiable marker (color, radioactivity, etc) to identify the hCG/hCG antibody complexes. It remains a very important means of testing in endocri.

Is it true that human chorionic gonadotropin only produced if you are pregnant?

HCG. Hcg, human chorionic gonadotropin, is produced by men and women. It is always present, all be it in small amounts. It is thought to be responsible for stimulating the gonads (testicles/ovaries) to increase production of certain hormones and is involved in the formation of the placenta. Urine HCG tests only tell you if its present but a blood test is required to give you it's concentration in blood.

What are the side effects of human chorionic gonadotropin (hcg)?

Ovulation. Hcg is a benign medication for most women. Ovulation is triggered with its use. There can be rare allergic reactions or burning with injection.
Depends. It depends if HCG is coming from a current pregnancy or as a medication given to help trigger ovulation in IUI cycles or help with oocyte maturation in ivf cycles.

What should I do if I miss a dose of human chorionic gonadotropin (hcg)?

Talk to MD. Human Chorionic Gonadotropin is used to initiate ovulation, which occurs in 36-44 hr after the injection. Timing may be off schedule if the dose is missed, so follow up with your doctor.
What treatment? Calling the doctor who prescribed it for you is always my #1 recommendation. The answer depends on why you take it - ovulation trigger in fertility treatments or ivf? Serial doses for luteal support? If you care to be more specific, I may be able to help more - but if this is an ongoing treatment contact your doctor before looking further here.

I know someone who wants to use hCG human chorionic gonadotropin diet. Is it safe?

500 cal/day?? The weight loss is due to the severe caloric restriction. In men with low testosterone and normal testicles, it may work better because the HCG will increase the testosterone level. In women, HCG may increase progesterone. Higher Progesterone may lead to less anxiety and therefore less eating. Overall, smart eating plus increased activity is a better choice.
See below. This was a diet that was promoted in the 1950's and then someone "rediscoverered" it and it has become just the latest diet fad. It did not work then and it does not work now. It restricts calories to 500 per day which is basically a starvation diet. This will cause weight loss initially but as soon as you go off of it the weight will rapidly come back due the suppressed metabolism.

Can you be pregnant if your human chorionic gonadotropin (hcg) levels are 0?

No. By definition, a elevated blood HCG level is pregnancy in some form.
You would not be! Hcg is produced immediately after implantation of the embryo and is the basis for all pregnancy tests. A level of zero-you can't be pregnant, assuming the test performed properly.

Can sinthetic hormones, norethisterone, clomiphene or chorionic gonadotropin cause TSH disbalance. In only 20 dys my TSH went from 3, 5 to 6, 5 mu/l?

No. Those hormones that you mention should not affect your thyroid function. You might ask your doctor to do a thyroid antibody panel to see if you have autoimmune thyroid disease.
