This study demonstrated refer instructions included test, these can confusing or difficult follow. Errors common, less than 25 % all steps correctly 47.3 performing multiple errors, particularly sample collection transfer. also difficulty interpreting results. To overcome issues, ideal requires pictorial are understand, simple integrated components, fewer steps, results interpret.
