Zinc
ZN
Description
"Zinc" test evaluates levels of this essential trace mineral in your blood to assess immune strength, wound healing, and metabolic health. Deficiency can lead to frequent infections, thinning hair, delayed recovery, or skin issues. Doctors often order this test when symptoms suggest poor absorption, chronic illness, or dietary gaps. Results help guide care strategies such as supplements or nutritional adjustments. Ongoing zinc monitoring supports enzyme function, cellular repair, and strong immune system performance.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
