Pregnancy can be detected in unit physical examinations, but the selection of physical examinations differs from unit to unit. If a female pelvic ultrasound is included in the program, it is possible to clearly find out the exact details of the pregnancy. If the early stages of pregnancy are less than forty days old and cannot be seen by ultrasound, it can indicate early pregnancy by measuring blood gonadotropin levels in the test program. Most of the physical examinations chosen by the unit are usually routine blood, urine, liver function, kidney function, blood lipids, blood sugar, quantitative hepatitis B plus hepatitis C antibody test, ultrasound of liver, gallbladder, spleen and kidney, and thyroid ultrasound. For men, prostate ultrasound, pelvic ultrasound, breast ultrasound, mammogram, hormone level measurement, cervical cancer screening for women, i.e. cervical fluid-based cytology and cervical papillomavirus test, etc. are also checked.
