Method Comparison
Method Comparison is a crucial process in medical and laboratory testing where professionals evaluate how well a new testing method matches up against an established one. Think of it like comparing a new recipe to a trusted family recipe to make sure it produces the same results. This process helps laboratories ensure that their test results are reliable and accurate, whether they're switching to new equipment, updating procedures, or validating their current methods. It's a key responsibility in clinical laboratories, diagnostic facilities, and research centers.
