A ureaplasma, gardnerella or mycoplasma clear result means you do not have the disease tested according to the test that you had. Doctorcall uses polymerase chain reaction (PCR) testing which is the latest and recommended test so you can consider yourself entirely clear.
A very recent exposure, before any infection has become established may still lead to injection. Condoms provide a good degree of protection against most sexual diseases.
