How Reliable is Laboratory Testing? | Lab Tests Online

Accuracy (Trueness) A test method is said to be accurate when the test value approaches the absolute "true" value of the substance ( analyte ) being measured. Results from every test performed are compared to known "control specimens" that have undergone multiple evaluations and compared to the "gold" standard for that assay, thus analyzed to the best testing standards available.
