Mycoplasma testing does not require fasting. However, there are several types of mycoplasma, among which Mycoplasma pneumoniae mainly causes respiratory symptoms, and its examination is mainly a blood test for IgM and IgG antibodies of Mycoplasma pneumoniae. It does not require fasting, but you should not eat too much fatty food. If you eat a lot of fatty food and have your blood drawn, there is a relatively small chance that the blood drawn will be fatty blood, and this situation will affect the test results. Another kind of mycoplasma is called Mycoplasma solium, which mainly infects the genitourinary system and can appear as purulent discharge from the urethra, when blood is not drawn, but the purulent discharge is taken for testing, because the purulent discharge is taken, so fasting or not fasting does not affect the test results.
