The viruses responsible for COVID-19 and common influenza (the flu) are similar in many ways. They are both respiratory illnesses, contagious when airborne, and have overlapping symptoms. However, since different viruses cause these illnesses, they differ in a few ways.

Blood glucose monitoring vs urine testing is a comparison many people make when they suspect they might have high blood sugar. While both tests can be indicators of the presence of diabetes, they produce results that offer diagnostically different information.
A pregnancy test detects a hormone called HCG (human chorionic gonadotropin). A woman’s placenta makes this hormone after a fetus has developed in her uterus. HCG is present in her blood and urine during pregnancy and not during any other time, which is why tests that detect it are the most accurate tests known for determining pregnancy. If you suspect you may be pregnant, choosing between a blood vs urine pregnancy test may be a tough choice.
