Immunosuppressive therapy

Screening

Before starting immunosuppressive therapy, consider the following investigations:

Tuberculin skin test
Strongyloides serology, if from endemic country
Hep B and C serology
Cytomegalovirus serology
HIV serology

Management

Latent TB infection: start treatment at least 4 weeks prior to starting the biologic
