Earlier diagnosis and treatment implementation leading to improved clinical outcomes | Performance claims: limitations, validation, evaluation in the hands of users, reliability and device failure |
Greater patient convenience and involvement | Specimens: appropriate sample collection, need for sample preparation prior to testing |
Smaller sample and reagent volumes, may be less invasive | Quality assurance and control: adequate training, tests performed by staff from a non-analytical background |
Easier access to service for those with limited mobility and for those who live in more remote areas with limited access to laboratory facilities | Operator-dependent steps:
Interpretation of instructions Inappropriate, insufficient or contaminated sample Use of test outside its specification Use of damaged, inappropriately stored or out-of-date reagents Incorrect interpretation of results Lack of awareness of limitations or interferences
|
Elimination of specimen transportation reducing time and costs | Incompatibility with laboratory results: reference ranges and results may differ, making comparisons difficult or absent |
Economic benefits with reduced number of clinic visits, reduced length of hospital stay and fewer admissions | Greater availability may encourage inappropriate or unnecessary testing |
Potential for earlier diagnosis may avoid some of the costs associated with undiagnosed infections | Patient anxiety:
|
Economic benefits could accrue with over-the-counter tests, allowing part of the financial burden of diagnosing STIs to be shifted from the public to the private purse for those who choose to buy a self-test | Cost:
Initial purchase Site alterations Training Maintenance Waste disposal
