Human chorionic gonadotrophin, or hCG, is a hormone that is produced by pregnant women. The purpose of hCG is to keep the corpus luteum, an ovarian cyst formed after ovulation that produces progesterone to sustain the pregnancy, from disintegrating. Levels of hCG in the blood vary depending on the stage of pregnancy and how the pregnancy is progressing; in a healthy pregnancy, they will double every 48 to 72 hours. Low levels of hCG may be an indication of a problem, such as poor implantation or an impending miscarriage. There are a few methods to raise hCG concentration; however, these methods may not prevent a developing problem with your pregnancy.
Avoid diuretics such as caffeine prior to taking your hCG test. This is particularly important for urine based hCG tests and over the counter home pregnancy tests. Diuretics can increase the speed liquids move through your system, which will dilute the amount of hCG in your sample.
Avoid drinking any liquid for at least four hours prior to testing. Consuming large amounts of liquid will dilute the level of hCG present, which can cause inaccurately low results.
For urine based tests, do not urinate for at least four hours prior to testing. This allows hCG to collect in the urine, raising the level present on the test.
Ask your doctor about prescription hCG injections. These medications are synthesized by the body, producing hCG.They are a common part of fertility treatment protocol and are used to induce ovulation and raise progesterone. Injections of hCG will cause a false positive result on both urine and blood pregnancy tests.
Take an hCG supplement designed for dieters. There are several dietary and weight loss supplements which contain hCG. These supplements should be used under the care of a doctor.
Using hCG can affect your fertility. You may experience irregular menstruation or serious side effects such as ovarian hyperstimulation, ovarian torsion and rupture. Use only under the care of a doctor.
