Diagnosis of gynecological infections involves a combination of patient history, physical examination, and laboratory tests. Common diagnostic methods include culture techniques, polymerase chain reaction (PCR), and antigen tests. For bacterial infections, a swab from the affected area is often cultured. Viral infections are diagnosed through PCR or serological tests. Fungal infections are usually identified through microscopic examination and culture, while protozoan infections can be diagnosed using wet mount microscopy.
