What Is a Zinc Deficiency Test?

A Zinc Deficiency Test is a simple blood test that measures the amount of zinc in your bloodstream to determine if you are getting enough of this vital mineral. 

A deficiency in zinc can affect everything from your energy and mood to your skin and immune system — yet it often goes unnoticed. 

At our clinic, we offer a fast and accurate zinc blood test, along with medical review and personalised recommendations to help restore optimal levels and support your overall health. 

What Is Zinc and Why Does It Matter?

Zinc is an essential trace element that plays a crucial role in: 

  • Immunity and infection resistance 
  • Wound healing and tissue repair 
  • Skin and hair health 
  • Hormonal balance (including testosterone and insulin regulation) 
  • Fertility and reproductive function 
  • Sense of taste and smell 

Even a mild deficiency can have noticeable effects on your health.

Symptoms of Zinc Deficiency

Many signs of low zinc are vague or easily attributed to other issues. You may want to get tested if you experience: 

    • Poor wound healing 
    • Hair loss or thinning 
    • Loss of appetite or altered taste 
    • Acne or skin rashes 
    • Fatigue or low energy 
    • Irregular menstruation or low testosterone 
    • Fertility issues
    • White spots on nails 

    What Causes Zinc Deficiency?

    Zinc deficiency can result from a range of dietary, medical, or lifestyle factors. Even if you're eating well, certain conditions may reduce zinc absorption or increase your body’s need for it.

    Common causes include:

    • Poor dietary intake: Vegetarian or vegan diets may lack sufficient zinc-rich foods (e.g., meat, seafood).
    • Digestive disorders: Conditions like Crohn’s disease, ulcerative colitis, or chronic diarrhoea can impair zinc absorption.
    • Chronic illnesses: Liver disease, kidney disease, diabetes, and cancer can increase zinc requirements.
    • High alcohol intake: Alcohol reduces zinc absorption and increases its loss through urine.
    • Pregnancy and breastfeeding: These life stages increase zinc demand.
    • Excess iron or copper supplements: Can interfere with zinc absorption if not properly balanced.
    • Older age: Seniors may absorb less zinc or have reduced appetite.

    Who Should Consider a Zinc Test

    You may benefit from a zinc deficiency test if you: 

    • Follow a vegetarian or vegan diet 
    • Have digestive conditions like IBS, Crohn’s, or celiac disease 
    • Are pregnant or breastfeeding 
    • Are recovering from surgery or wounds 
    • Take medications like diuretics, PPIs, or iron supplements (which may affect zinc absorption) 
    • Have unexplained fatigue, skin problems, or frequent illnesses

    General

    Do I need to stop taking supplements before the test?
    Yes. Zinc supplements or multivitamins can affect your results. Avoid supplements for at least 24 hours before testing, unless advised otherwise by your doctor.
    How long do results take?
    Typically, 5–7 working days.
    What is considered a normal zinc level?
    Normal serum zinc is usually between 70–120 µg/dL, but reference ranges may vary slightly by lab. Values below this may indicate zinc deficiency or suboptimal status. Serum zinc levels below 70 mcg/dL in women and 74 mcg/dL in men indicate inadequate zinc status.
    What happens if my zinc levels are low?
    Our doctor may recommend:
    • Zinc supplementation (form and dose depend on severity)
    • Dietary changes — adding zinc-rich foods like red meat, seafood (especially oysters), eggs, nuts, seeds, and legumes
    • Treating underlying absorption issues, if relevant
    Can high zinc levels be harmful?
    Yes. Excess zinc from over-supplementation can lead to:
    • Nausea or vomiting
    • Lower immunity
    • Copper deficiency
    • Imbalance in other minerals
    Always follow our doctor’s recommended dose.
    Can stress affect my zinc levels?
    Yes. Chronic stress and inflammation can affect how your body uses and stores zinc, potentially increasing your needs.
    Can children or teens be tested for zinc deficiency?
    Yes. Zinc is especially important for growth and immune development in children and adolescents. If there are signs like frequent infections, poor appetite, or delayed growth, testing may be appropriate.
    Can zinc deficiency make my skin worse?
    Yes. Zinc is essential for wound healing, skin regeneration, and reducing inflammation. Low zinc may worsen:
    • Acne
    • Eczema
    • Dermatitis
    • Slow healing cuts or ulcers
    How long does it take to correct a zinc deficiency?
    Mild deficiencies may improve within 2–4 weeks of proper supplementation. More severe or chronic deficiencies may take 2–3 months or longer, with follow-up testing recommended.
    Can I take zinc long-term?
    It’s safe to take zinc supplements short term under medical supervision. Long-term high doses can lead to copper deficiency or mineral imbalances. Always follow recommended dosages.
    What happens if I have too much zinc?
    Excess zinc, usually from over-supplementation, can cause nausea, vomiting, abdominal cramps, headaches, and diarrhoea. Long-term high intake may lower immunity, cause copper deficiency, and disrupt the balance of other essential minerals. Always follow recommended dosages.
