Self – Testing for HIV Infection
Only US FDA approved in Home HIV testing kit which used similar technique of Western Blot
Used by over a million consumers and same device used by health care professionals recently
The technique is simple oral swabs, no blood, and results will be in 20 minutes
24 bilingual customer phone support and details product website offering information, referrals to care, product usage instructions and more
Higher consumer satisfaction
Self – testing adoption
Influenced by user’s perception of costs, benefits, personal need and convenience.
Users greatly prefer painless oral testing over finger stick or venepuncture
Additional benefits include increased confidentially, privacy and reduced social stigmatization
Self – testing Fidelity
Original studies by manufacturer < 2 % failure
- Limited by use of select population (MSM)
- US adult vs trained providers ( Sensitivity 92.9% vs 99.3 % )
Singapore, error rate 0.6 %
Atlanta, 9 % error rate
China (non – Oraquick) 10 % difficulty swabbing, 17.5 % difficulty reading results
In NYC young MSM and transgender women reported concerns of anxiety, test correct use and instructions
Self – testing Dissemination – Los Angeles
- Vending machines
- US Priority mail
Vending Machines in sex clubs which are located at private areas with self – contained unit that can be monitored remotely as well as posted instruction how to use the kit
Initial Concerns for Vending Machines
· Cost of HIV home test kits
· Emptying the vending machine
· Conflict with existing testing programs
· Home test kit window period
· Result anxiety
Results summary over 7 weeks, in 2014
- 1176 hours and 312 tests for Vending machines versus 64 hours with 58 tests for traditional testers with clinicians
Providing Vouchers for the free test kit that can available at Pharmacy is also very positive outcome
Social Medical Promotion commenced since 2014 through Periodic advertisements
In General, among three choices; vouchers, vending machine, priority mail to home
Approximately 2/3 used Mail services and 1/3 of other consumers accessed through free vouchers, 67 % and 30 % respectively. Only 3 % used vending machine to get the self – testing kit
Linkage to care for community
HIV Self- test added as a reported element in HIV Surveillance and also follow up management goes through by receiving the positive test kit photos taken by consumers
