Laboratory tests, whether blood tests, swabs, or urinalysis, are another great diagnostic tool for doctors and patients alike! That said, such value is often lost on many individuals who are unaware of how lab tests can help them or not sure when it is an appropriate time to request lab testing. If you experience unusual and persistent symptoms, such as significant or sudden fatigue, difficulty sleeping, abnormal weight gain, or new pain, a lab test can get to the bottom of what is bothering you! Lab tests are also helpful for preventative measures and optimizing your health, as they can determine if you have any vitamin or mineral deficiencies, if you are prone to high cholesterol or blood sugar levels, or if you are more prone to any diseases. This knowledge can help you make appropriate lifestyle changes to accommodate your bodily deficiencies or tendencies and reduce your likelihood of illness or complications.
