Throughout the course of a medical diagnosis, members of your health care team will order different laboratory blood tests. Many times, these laboratory blood tests will be repeated throughout the diagnosis, treatment, follow-up, and continuing care. Each medical diagnosis and treatment has specific factors that are required to be monitored. When it comes to the results of these tests and what counts are normal or not, it is important to know that “normal” ranges simply reflect average values in a population. It is common for some tests to be slightly outside of the “normal range” (low or high) without consequence and your clinicians can guide you with respect to their relevance.
