Final answer:
The most common POCT chemistry test is urinalysis using test strips, which detect various substances in urine. Lateral flow tests for pregnancy and other conditions are also widely used, alongside blood tests for lipid and glucose levels.
Step-by-step explanation:
The most common chemistry test performed via POCT (Point-Of-Care Testing) is likely to be urinalysis using test strips. These strips indicate the presence and concentration of substances like glucose, proteins, ketones, and pH levels in urine, which are crucial for diagnosing various health conditions. During the process, chemical reagents on the test strips react and change color, which must be read at the proper time to ensure accurate results. Additionally, immunochromatographic assays, or lateral flow tests, are widely used for quick diagnostics, including pregnancy tests that detect human chorionic gonadotropin (hCG), and the TORCH screening. For blood analysis, common tests include those measuring lipid or glucose levels in plasma, and HPLC techniques are often employed for bioanalysis and compound quantification.
