Laboratory testing is a science professionally conducted with rigorous statistical analysis and quality controls. But medical diagnosis has been called an art, a clinical reasoning process, not always clear cut, which relies on information from multiple sources. Medical testing is an important component in the diagnostic tool kit, and very often an invaluable tool, but it is most reliable when used in conjunction with other meaningful data collected in the diagnostic process. Modern medicine relies on the combined skills of Clinicians and diagnostic laboratories to manage a patient’s illness. At the heart of laboratory is the care of the patient. The laboratory must produce accurate and reliable results quickly in response to their clinician’s request.
A patient who does not follow preparation instructions or provides insufficient information to the physician undermines the entire quality assurance effort for a specific test. You can put great trust in the data generated by today's exacting medical tests. A caveat to remember is that a diagnosis and treatment plan for a serious disease should never be based on a single medical test. Test findings are just one of the pieces of the diagnostic puzzle. Please follow test preparation instructions carefully and tell the person collecting your sample about any exceptions you made.
