Zinc is the most vital mineral for the body to fight infections and produce cells. It is key to create DNA and heal injuries. Lack of correct zinc levels can lead to many side effects amongst which are lowered sense of smell and taste. The only way to know if your zinc levels are normal is the Zinc deficiency test. Let us know how it is done and what are the normal zinc levels in a healthy person.

What Is Zinc Deficiency?

In the simplest terms, zinc deficiency is the situation wherein the body has no adequate zinc levels to meet its daily needs. There may be many reasons for this condition, however, one of the most common reasons is not getting enough zinc through the food one eats.

Symptoms Of Zinc Deficiency

The body needs zinc as said above for cell production besides carrying on immune functions. Apart from these two vital functions zinc is also a key mineral for sexual development, reproduction, and growth.

When the body is deficient in zinc the body cannot produce new and healthy cells thereby leading to the below symptoms such as;

  • Inexplicable weight loss
  • Wounds that do not heal
  • Absence of alertness
  • Reduced sense of taste and smell
  • Diarrhea
  • Loss of hunger
  • Open sores on the skin
  • Frequent signs of the common cold
  • A weakened immune system
  • Predisposition to infections
  • Skin rashes around the mouth
  • Skin ulcers
  • Vision problems
  • Hair loss
  • Sexual dysfunction
  • Difficulty concentrating
  • A disposition to recurrent asthma exacerbations

The zinc deficiency effects above said are not complete and may also include others as zinc deficiency is also the result of other medical treatments and mineral deficiencies. Usually, zinc deficiency is high in pregnant women and nursing women.

Can You Test For Zinc Deficiency?

Yes, zinc deficiency can be tested. When in doubt, zinc deficiency can be tested with the help of a urine test, hair analysis test, or blood test. Due to numerous causes of zinc deficiency one single test may not be sufficient to know the exact zinc deficiency range and cause behind it. Testing blood plasma is often the most reliable way to know the deficiency of zinc.

The zinc deficiency test at home can also be done and one simple way to know if your body is less in zinc then you must mix 50mg of zinc sulfate in a half a glass of water and drink it. If it tastes sweet, pleasant, or tasteless such as water, then it indicates less zinc and that the body requires it. In case the taste is unpleasant or strong metallic it indicates that one isn’t deficient in zinc.

This kind of zinc deficiency test done at home is known as the ‘’sweet test”.

How Is The Zinc Deficiency Test Done?

The biggest problem with diagnosing zinc deficiency is, it is present in small traces in the cells of the body. A lab technician may suggest a urine test or blood test to know the zinc levels. They may even ask full health history besides asking questions about dietary intake.

A blood test is done using the blood drawn from a person’s veins and a urine test is done using a person’s urine.

Analysis of hair strands may also be done.

Normal Levels Of Zinc Deficiency

The normal level of zinc in matured persons is 70 mcg/dl (normal 70-120 mcg/dl) and as such anything less than this is known as zinc deficiency. Zinc deficiency can even be linked with less alkaline phosphatase.

There are two main causes of low zinc levels;

  1. Medical conditions
  2. Dietary habits

  • A vegetarian diet
  • Iron supplements (interfere with zinc levels)
  • Babies breastfed exclusively
  • Intake of medicines like antibiotics, diuretics, and penicillamine

Besides the above, age is also one condition that leads to lesser zinc presence.

Causes Of High Levels Of Zinc
