Urine-based laboratory pregnancy tests are more accurate than home tests and can confirm the presence of the hormone HCG, which is produced during pregnancy. Although blood tests can also detect HCG and determine the approximate age of the fetus, in most routine clinical confirmations of pregnancy, a urine-based laboratory test is sufficient, non-invasive, and cost-effective. Blood tests are typically used for more detailed assessment and monitoring once pregnancy is established. Ultrasound is not the best initial confirmation method but is later used to assess fetal development.
