HCG Beta Total, Tumor Marker

The HCG Beta Total, Tumor Marker test measures the level of human chorionic gonadotropin (HCG) hormone in the blood. It is produced by the placenta and is normally detected in the blood during pregnancy. However, HCG may be elevated in men or non-pregnant women in certain types of cancers, including cancers of the liver, lung, pancreas, and stomach. 

HCG, also known as Beta HCG, is not present in men or non-pregnant women under normal conditions. However, in some cancers, this hormone may be produced, thereby serving as a useful tumor marker. HCG concentrations in the blood may be increased in various gestational trophoblastic diseases (a group of tumors that develop during the early stages of pregnancy), and germ cell tumors (tumors in ovaries and testicles). HCG levels are also seen to be elevated in other cancers such as liver, neuroendocrine, breast, ovarian, pancreatic, cervical, and gastric cancers as well as in non-cancerous conditions such as cirrhosis, duodenal ulcer, and inflammatory bowel disease. 

The HCG Beta Total, Tumor Marker test may be advised when an individual has symptoms including bleeding or discharge not related to periods (menstruation), larger-than-usual uterus while pregnant, abdominal or pelvic pain, high blood pressure, or swollen hands and feet early in pregnancy or prolonged vaginal bleeding after childbirth or miscarriage. Please note that the HCG Beta Total, Tumor Marker test is not intended to confirm or monitor pregnancy.

In men, HCG may be advised in case of a solid and firm lump in a testicle that grows bigger (with or without pain), pain or heaviness in the scrotum, groin pain, oddly shaped testicle, back pain, etc. Additionally, doctors may use this test to evaluate the effectiveness of treatment for gestational trophoblastic disease or germ cell tumors and to check for their recurrence. However, HCG should not be used to screen the general population for germ cell tumors.

Generally, when an individual is diagnosed with ovarian germ cell cancer or testicular cancer the HCG Beta Total, Tumor Marker test is prescribed by the doctors to give a better prognosis of the condition. Often, this test is done along with other blood tests to confirm the diagnosis.

No special preparation is required before the HCG Beta Total, Tumor Marker test. However, it is important to provide a brief clinical history or doctor's prescription at the time of sample collection. 

Lab test results may vary across different laboratories. For serial/repeat testing, it is advisable to repeat tests at the same lab as test values may vary depending on the assay method used. HCG values, regardless of levels, should not be interpreted as absolute evidence of the presence or absence of disease. All values should be correlated with clinical findings and results of other radiological investigations.

Abnormal test results require an expert interpretation, therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for proper understanding of the test results. The insights from the HCG Beta Total, Tumor Marker test are valuable in the pursuit of an accurate diagnosis and effective management of various cancerous and other non-cancerous conditions.
