The β-HCG levels are typically reported in units such as milli-international units per milliliter (mIU/mL). The presence and concentration of β-HCG in the blood can indicate pregnancy. In early pregnancy, β-HCG levels rise rapidly and can be detected in the blood before they appear in urine-based pregnancy tests.

It’s important to note that β-HCG testing can also be used to monitor the progression of pregnancy and assess for potential issues such as ectopic pregnancy or miscarriage. Additionally, β-HCG testing may be used in non-pregnancy-related contexts, such as to assess and monitor certain types of tumors that produce β-HCG.
