Interpretation of Blood Test Results

Blood test results should be interpreted by a qualified healthcare professional who is familiar with your individual medical history. Normal ranges can vary slightly depending on the laboratory performing the test. It's important to note that values outside of these ranges may not always indicate a medical problem, as they can be influenced by factors such as diet, exercise, and medications.
