What is the possibility of false negative gonorrhea urine test while on an antibiotic for a day and half?

What kind of test?: A culture is more likely to give a false negative result due to antibiotics. A DNA test is not likely to be affected. 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. Drink enough water daily, so that your urine is mostly colorless. 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.
