Severe symptoms like sudden, unexplained hair loss, persistent diarrhea, or significant changes in taste and smell should prompt a call to your clinician. For very high levels, severe nausea, vomiting, or abdominal pain warrant urgent medical advice.
This test checks how much zinc is in your blood. Zinc is a key mineral. It helps your body fight off sickness. It also helps cuts heal. Zinc helps you taste and smell too.
Your doctor orders this test to see if you have too little or too much zinc. This is important if you get sick often, if your cuts heal slowly, or if your sense of taste has changed.
Reference ranges for zinc can vary by laboratory and may depend on factors like age. Your results should always be interpreted by a healthcare professional.
