Which chemistry test is reported to be most commonly performed by means of point-of-care testing (POCT)?

Glucose testing is the most commonly performed chemistry test through point-of-care testing (POCT) due to its critical role in managing diabetes and monitoring blood sugar levels. Point-of-care testing allows healthcare providers to obtain rapid results directly at the site of patient care, which is vital for making immediate clinical decisions.

Given the high prevalence of diabetes and the need for frequent glucose monitoring, this method provides convenience and efficiency, allowing patients to receive timely treatments and adjustments to their management plans. The technology involved in glucose testing has advanced significantly, with devices that are easy to use, provide quick results, and require minimal training.

While cholesterol, electrolytes, and blood urea nitrogen testing are important, glucose testing stands out due to its versatility, ease of performance, and the direct impact it has on patient care outcomes, particularly in acute and chronic settings.
