It is highly unlikely for hCG not to show in blood if a person is pregnant. Blood tests can usually detect lower levels of hCG than urine tests. However, very early in pregnancy, hCG levels might still be too low for detection. If pregnancy is suspected but not confirmed by a blood test, it may be advisable to repeat the test after a few days or consult a healthcare provider.
