Factors associated with hepatitis C and HIV testing uptake among men who inject image and performance enhancing drugs.

The majority were untested for HCV/HIV. HCV/HIV testing and risks were associated with recruitment through services. Previous needle and syringe program-based studies have potentially overestimated testing uptake and underestimated risk. Targeted interventions are needed, particularly for those not accessing services. The association between HCV/HIV testing uptake and receipt of metabolic tests suggests that developing a combined offer of these tests as part of health monitoring could improve uptake.
