One other main problem is the shortage of a supplier middle for pharmacists – who will not be immediately compensated for offering point-of-care testing providers.4 Lastly, the documentation of pharmacist-led point-of-care testing in digital medical information and most of the people well being system could trigger an operational drawback.
