Why fast for tests: Fasting blood tests are used to get an idea of what your lipid and glucose levels are. If your lipids are elevated on a fasting blood sample, you need dietary, k exercise and/or drug therapy to control their levels. If you fasting glucose is normal, that does not rule out diabetes. Another test called a hemoglobin a1c will give you a better idea of your have diabetes if it's elevated.

Yes: Fasting blood test is routinely done especially for blood sugar and lipid panel.

No: There are separate tests for each of the sexually transmitted infections. There is no well defined panel of "regular" blood tests. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.

Most blood tests do not require fasting. Some STD's can be found with blood tests, some cannot. Exactly which infection concerns you?
