Aknede Tanısal Testler

Abstract

In patients with acne, clinical characteristics and anamnesis determine the tests to be ordered. The aetiology of acne is multifactorial. Both sex hormones and metabolic hormones may play a role in the development and severity of acne. From the hormones that may be associated with the aetiopathogenesis of acne, androgens [testosterone, dehydrotestosterone (DHT), and dehydroepiandrosterone sulphate (DHEAS)] are the hormones that influence sebum production most. Although there are not any comorbid endocrinologic diseases in most of the patients with acne, detection of any endocrinopathy is important. An endocrinologic examination is required in female patients with acne in the presence of any characteristics suggesting hyperandrogenism. The necessity of specific, non-standard culture for P. acnes prevents performing routine cultures. One particular case where microbiological sampling is useful in patients with acne is when gram-negative folliculitis is suspected. Cutaneous staphylococcal infections should be considered for differential diagnosis especially in acute lesions and cultures should be taken.
