Diagnosis
Tests And Diagnosis
In the diagnosis of jock itch, a physical examination of the affected region is first done and a skin swab is taken with a scalpel and examined under a microscope. This is a potassium hydroxide (KOH) test that is done to determine the presence of any fungi or yeast that could have caused the infection.
If the KOH test produces a negative result, there still may be a chance that fungi are present and a lab culture would need to be done to see if there is a growth of fungi during the test. If the KOH test produces a positive result and clearly shows the presence of fungi, then anti fungal ointments or medications may be given to the affected person.
Your doctor may also recommend a skin biopsy to eliminate other possible conditions that could cause the symptoms experienced. Apart from these tests your doctor may also enquire about your medical history and sexual history such as your HIV status, usage of public swimming pools, sports activities and pets at your home. Areas of your body that are not affected by the infectionsuch as the armpits, feet, and the genitals may also be examined by your doctor.
