Which disease is commonly tested using point-of-care testing (POCT)?

Diabetes is commonly tested using point-of-care testing (POCT) due to the need for frequent monitoring of blood glucose levels. POCT allows for immediate results, enabling patients to manage their condition more effectively and make timely decisions regarding their insulin or dietary adjustments. This immediacy is critical for diabetes management, as fluctuations in blood sugar levels can have a significant impact on a patient's health. Tests such as fingerstick blood glucose monitors and hemoglobin A1c tests can be performed quickly in a variety of settings, increasing accessibility for patients.

In contrast, while heart disease, asthma, and Alzheimer's disease are significant health concerns, their management and testing often require more extensive evaluation or monitoring that may not be suitable for the rapid testing environment of POCT. For example, heart disease may involve comprehensive assessments that include EKGs and cholesterol testing, asthma may require spirometry, and Alzheimer’s disease typically necessitates cognitive assessments and possibly neuroimaging for diagnosis. Therefore, diabetes stands out as a condition that aligns well with the principles and practicalities of point-of-care testing.
