BACKGROUND
The pregnancy is a condition where the levels of HCG in the body is elevated and can be detected in either urine or blood. The urine pregnancy test is the most common method used for home pregnancy confirmation. This test is taken 1 week after the missed period and usually provides the confirmation on pregnancy. If in doubt, the blood pregnancy test provides the confirmation as it detects the values of HCG in blood. The detection of HCG <5 mlU/ml it is considered as negative and detection of HCG between 5-25 mlU/ml is considered as equivocal and the test to be repeated again to confirm pregnancy.1

The needle is inserted and the blood is collected in a tube. Post collection of the blood, the elastic band and needle are removed and cotton gauze is placed at the puncture site to prevent the oozing of blood from the puncture site.
