How Is Folliculitis Diagnosed?
The diagnosis of folliculitis usually involves a combination of physical examination, medical history, and laboratory tests. Here are some common diagnostic tests used to identify folliculitis:
- Physical examination: A dermatologist will examine the affected skin, looking for signs of inflammation, such as redness, swelling, and pustules. They may also look for signs of hair loss or scarring.
- Skin culture: A sample of the affected skin may be taken and sent to a laboratory to identify the specific bacteria or fungus causing the infection. This test can help determine the most effective treatment.
- Blood tests: A complete blood count (CBC) or erythrocyte sedimentation rate (ESR) test may be ordered to rule out other conditions, such as lupus or other autoimmune disorders.
- Biopsy: In rare cases, a skin biopsy may be performed to confirm the diagnosis and rule out other conditions.
- Allergy testing: If an allergic reaction is suspected to be the cause of the folliculitis, patch testing or other allergy tests may be performed to identify the allergen.
Overall, a combination of these diagnostic tests can help identify the cause of folliculitis and guide appropriate treatment.
