The Proficient Testing (PT) schemes under Clinical Chemistry were stopped from operation since 2013. This was due to challenges on preparation of stable PT samples as the technologies used were poor. PT samples produced at NHLQATC were not maintaining the stability over the long period of time of shipment lower to testing Laboratories.
Currently the NHLQATC is under process to resume PT services that will cover various analytes. Testing Laboratories receiving PT samples will be communicated through the appropriate channel. Any other Laboratories willing to participate are required to submit a request stipulating the scope of their tests needed to be enrolled.
