Pregnancy tests most are made with a urine sample because it is easier to collect from a blood sample. The presence of the hormone hCG is detected by many urine assay type methods. Most are based on a reaction between the hCG and the hCG antibody. A second reaction is absolutely necessary to ensure that the first reaction takes place. This reaction is often a color change. Some women prefer pregnancy tests at home. These are packages that can be purchased at the pharmacy.
