The study surveyed 130 dermatologists specializing in hair disorders from 14 countries to assess the practice of laboratory testing in alopecia areata (AA). Despite international guidelines suggesting that investigations are unnecessary for asymptomatic patients, there is significant variation in practice among experts. The survey found that 51.5% of respondents routinely performed screening blood tests for coexisting autoimmune illnesses, while 39.2% screened for contributory conditions like nutritional deficiencies. Before starting systemic therapies, a high percentage of dermatologists ordered various tests, including full blood counts and liver function tests. The study highlights the variability in real-world practices and suggests a need for renewed discussion on laboratory testing in AA.
