Neisseria gonorrhoeae negative means that no gram-negative diplococci are seen in polymorphonuclear leukocytes or gonococcal culture is negative, or gonococcal nucleic acid test is negative, which indicates that gonorrhea is not present, if there are no clinical symptoms such as pus from the urethra and the test for Neisseria gonorrhoeae is also negative. If there is discharge from the urethra, but the test for Neisseria gonorrhea is also negative, it is necessary to do some other tests for other pathogens, such as Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma genitalium, Mycoplasma hominis, and other tests for other pathogens.
