Zinc – what do your levels mean?
Have you had your zinc levels measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what high or low levels can signify, and when it makes sense to get tested.
What is the normal range for Zinc?
What is the normal range for Zinc?
The normal range for zinc in plasma is between 10-19 µmol/L. This interval may vary slightly depending on the laboratory's measurement methods, but values within this range are generally considered normal. Zinc levels can be affected by factors such as age, gender, and time of sampling. For example, values are often higher in the morning and can decrease by up to 10-20% after a meal. It is important to note that zinc levels close to the boundaries may indicate early deficiency or excess, which may require further investigation.
What does a low level mean?
A low level of zinc can lead to symptoms such as fatigue, reduced sense of taste, slow wound healing, hair loss, and skin problems like acrodermatitis enteropathica. Causes include malabsorption, chronic diseases such as inflammatory bowel disease, alcoholism, or inadequate nutrition. Particularly vulnerable groups include the elderly, pregnant women, vegans, and individuals with chronic diseases. If zinc deficiency is suspected, a doctor should be consulted to have the level measured and possibly adjust the diet or take supplements.
What does a high level mean?
Elevated zinc levels can be a sign of toxicity, often due to excessive intake of zinc supplements or occupational exposure to zinc fumes. Symptoms include nausea, vomiting, diarrhea, headache, and dizziness. Prolonged exposure can lead to more serious health problems such as immunosuppression. It is important to seek medical attention if these symptoms occur, especially if there has been exposure to potential sources of zinc poisoning. Treatment typically involves removing the source of exposure and possibly symptomatic treatment.
