Test Details

Additional Information

Quantitative HCG (human chorionic gonadotropin) helps confirm a pregnancy by measuring the amount of HCG in the blood as early as 7 days after conception. This hormone is produced by the placenta (an organ that develops in the uterus during pregnancy) and increases steadily throughout the first trimester (8-10 weeks) of a normal pregnancy. 

This quantitative test is highly accurate; if HCG reaches the detectable limit of more than 5 ml U/mL, a confirmed pregnancy is very likely. However, the results should be confirmed with a healthcare provider. If the test result is less than 5 ml U/mL, either there is no pregnancy, or the test may have been conducted too early and requires repeating after a few more days. As with urine/home pregnancy tests, false results (both negative and positive) are possible outcomes from a blood pregnancy test.  

The HCG blood test is performed to: 

  • confirm pregnancy 
  • determine the approximate age of the fetus 
  • diagnose an abnormal pregnancy, such as an ectopic pregnancy 
  • diagnose a potential miscarriage 
  • screen for Down syndrome 

The HCG blood test is sometimes used to screen for pregnancy before a person undergoes certain medical treatments that could potentially harm a developing baby. Examples of these treatments include X-rays. 

If an HCG test concludes that a person is pregnant, healthcare professionals can ensure that they’re protected and that the fetus isn’t harmed by those medical treatments.

Statement on Medical Necessity
All ordered tests should be medically necessary for the diagnosis or detection of disease, illness, impairment, symptom, syndrome, or disorder and the results should be used in the medical management and treatment decisions for the patient. Solaris requires ICD-10 codes with each order for lab testing and both the tests ordered and the diagnosis should be documented in the provider’s medical record for the patient. The United States Department of Health and Human Services, Office of Inspector General, takes the position that a provider who orders medically unnecessary tests may be subject to civil penalties.

Panels and Profiles
Solaris offers Providers the convenience of ordering test combinations in a group at times with the flexibility to choose appropriate test(s) for individual patients. Providers should only order those tests that he or she believes are medically necessary for each patient, and a lesser inclusive profile or individual tests should be ordered if not all tests in the test combination/profile are medically necessary. All tests offered in a test combination/profile may be ordered separately as individual tests. Solaris encourages clients to contact their Solaris representative if the testing configurations shown do not meet individual needs for any reason, or if some other combination of procedures is needed.
