What does quality control ensure in laboratory testing?

• A. The speed of testing
• B. The accuracy of the test being administered.
• C. The cost of reagents
• D. The novelty of equipment

Answer: (B)

Quality control in laboratory testing is about making sure results are accurate and reliable. It achieves this by checking the testing process with known standards and controls: calibrating instruments, running positive and negative controls with each batch, and repeating measurements to assess precision. These checks catch problems like faulty reagents, instrument drift, or procedural errors before results are reported, so patient care isn’t misled by incorrect data. Speed, cost of reagents, or the novelty of equipment aren’t the primary focus of quality control; they’re separate considerations. The main point is producing trustworthy, reproducible test results.
