Abstract
Background: Home-based sampling could create accessible testing opportunities for men who have sex with men (MSM) who use pre-exposure prophylaxis (PrEP). Blood collection is required for the most reliable laboratory results for HIV and syphilis testing. An innovative blood collection method (Tasso+) creates a vacuum and semi-automatically collects larger volumes of blood from the upper arm. This study aimed to assess acceptability and feasibility of this device among PrEP-using MSM and the performance of blood collection.
Methods: Between August 2022 and January 2023, 47 MSM were recruited during their routine PrEP consultations at a Dutch Centre for Sexual Health. Participants tested the method directly after consultation, and an online questionnaire determined acceptability and feasibility. Blood and residual serum volumes were measured after sampling and after HIV and syphilis testing.
Results: Of the participants, 87% had a positive attitude toward use of the device, and 77% would use it again for self-sampling at home. Participants rated the use of the blood collection device as easy (96%). On average, 536 μL whole blood (244 μL serum) was collected. All samples were tested for HIV and syphilis, and most samples had sufficient blood for routine HIV (91%) and syphilis testing (89%). Most samples (85%) had 220 μL residual blood, sufficient for further testing (e.g., confirmation).
Conclusions: Blood self-sampling with a method that creates a vacuum from the upper arm is highly acceptable by users and performs well in blood collection for multiple tests. This method has promising potential for use in home-based sexual health care for PrEP-using MSM.
