Emerging Infections Network Survey of Screening for Cryptococcal Antigenemia, United States, 2024

Abstract

We polled infectious disease specialists about cryptococcal antigen screening for patients initiating HIV antiretroviral therapy. Of 215 respondents, 33% reported typically obtaining screening for patients with CD4 counts <200 cells/mm3 and 63% for counts <100 CD4 cells/mm3. Uncertainty about cryptococcal antigen screening benefits and recommendations suggests opportunities for education and increased screening.
