Which statement reflects a disadvantage of some POCT tests?

The statement about high cost reflects a disadvantage of some Point-of-Care Testing (POCT) tests because while these tests are designed to be convenient and provide quick results at the site of patient care, many of them can be significantly more expensive than traditional laboratory testing. This cost factor can pose a barrier to their widespread adoption, especially in resource-limited settings or for facilities operating with tight budgets.

In contrast, perfect accuracy is not a characteristic of POCT; many tests may have limitations in sensitivity and specificity. Immediate results are actually an advantage of POCT, as they allow for timely clinical decision-making. Universal applicability does not apply because not all tests are suitable for every patient population or condition, and some may be limited in terms of their intended use. Therefore, high cost stands out as a notable downside to the benefits offered by POCT.
