The two types of pregnancy test are the urine test and blood test, according to WebMD. These tests detect any presence of human chorionic gonadotropin hormone, which is produced after fertilized egg attaches to the uterine wall.
Home pregnancy tests are private and convenient, states WebMD. Women prefer to undergo home pregnancy tests after missing their first period, before proceeding to a doctor for more accurate results. Women should follow the instructions on testing carefully for accuracy.
Blood can show pregnancy within a period of about seven days, states WebMD. Blood tests can detect human chorionic gonadotropin earlier than urine tests. Types of blood test include a qualitative human chorionic gonadotropin test, which detects this hormone, and a quantitative human chorionic gonadotropin test, which shows the amount of this hormone in the blood.
