Final answer:
An HCG test should be performed on all patients who have the potential to be pregnant based on their age, reproductive organs, and menstruation status. This includes patients across a spectrum of gender identities with reproductive capabilities, including transgender males and non-binary individuals with a uterus. HCG is the hormone detected in pregnancy tests to confirm pregnancy.
Step-by-step explanation:
An HCG (Pregnancy Test) should be performed on all patients who are in the reproductive age range and have the physiological capability to become pregnant. This includes: A) Patients who are 12-49 years of age, B) Transgender males with a uterus, C) Females who are over 49 and still menstruating, D) Gender non-binary individuals with a uterus, and E) All of the above. It is essential to assess for pregnancy in these groups as situations like ongoing menstruation, hormone treatments, and gender identity should not exclude individuals from proper medical diagnosis and care.
HCG, or human chorionic gonadotropin, is a hormone that plays a crucial role in pregnancy. It is produced by the chorion of the zygote following conception and helps maintain the corpus luteum and elevated levels of progesterone. Pregnancy tests measure the level of β-HCG in urine or serum to determine if an individual is pregnant by detecting the presence of this hormone.
