How it works

~ Made in the USA for Accuracy~

Breast Milk Test Strips shows the amount of Zinc, Calcium and Protein in breast milk. These parameters are all important to test because they provide infants a strong immune system, rapid cell growth, healthy development and strong muscles and bones.


Human milk is made up of whey and casein proteins. The main building blocks for strong muscles and bones. Some proteins serve a wide range of other functions such as defense against harmful bacteria and viruses.

Calcium is important for your baby's bone development. A low calcium intake can contribute to the development of rickets. Some studies show that mother's breast milk calcium bioavailability is greater than cow’s milk and baby formulas.

test strips

One strips tests all three  - Protein, Calcium and Zinc.


Zinc is one of the most important micronutrients in breast milk. Infants need large quantities during the first month to support growth, immune function, and cognitive development. Yet despite zinc's importance, pediatricians aren't trained to detect the symptoms of its deficiency. (See FAQ below for more details)

Questions & Answers

How does it work?

1. Collect breast milk in a clean glass or plastic container. 

2. Test milk sample as soon as possible after collection. Refrigerate milk sample immediately if the sample cannot be tested within one hour. Bring refrigerated sample to room temperature and mix thoroughly before testing. 

3. Allocate a small portion of the breast milk sample into another container for testing in order to avoid contamination of the whole milk sample. Do not dip the test strips directly into the primary collection container. 


4. Completely dip strips so that the testing pads are submerged in the fresh, well-mixed breast milk. Remove the strip immediately to avoid dissolving out the reagent areas.

6. While removing, touch the side of the strip against the rim of the milk container to remove excess breast milk. Blot the lengthwise edge of the strip on an absorbent paper towel to further remove excess liquid and avoid running over (contamination from adjacent reagent pads).


 7. Wait for 1 minute and compare results to color chart.Note: Breast Milk nutrient make up changes through the day. It’s advised to test 2-3 times a day over a 3 day period to get a better overview on your breast milk nutrient content.  

How many times should I test the breast milk?

Breast milk nutrient make up is not consistent, even during the same feeding. We suggest to test the milk a few times a day for 3 days. This will give you a better average on your milk's nutrient composition.

Why is Zinc important in breast milk. Can you give me a detailed explanation?

Zinc is one of the most important micronutrients in breast milk: Infants need large quantities of it during the first months of their lives to support growth, immune function and cognitive development. Yet despite zinc's importance, pediatricians aren't trained to detect the symptoms of its deficiency as of yet. We dope that will change in the near future. 

Researchers in Penn State may have found a way to recognize women who are at risk of having low milk zinc levels. The team has identified a mutation in a particular zinc transporter -- called ZnT2 -- that cause defects in the milk-secreting mammary epithelial cells. This mutation causes women to have severe zinc deficiencies in their breast milk -- about a 75% reduction. 

About 60% to 80% of women across the world are thought to be marginally zinc deficient just because of their diets per the Penn State research. In their experiment with mice, they found that it only takes a slight zinc deficiency to have profound consequences on mammary gland development, the ability to lactate, and the effectiveness of involution. Now they’re trying to understand why. 

Research found that the amount of zinc in your diet does not affect the amount of zinc that makes its way into breast milk. There is no evidence that milk zinc concentration can be affected by your diet so taking zinc supplements may not help. The research continues by suggesting that milk zinc levels may have more to do with whether or not you have genetic variation in ZnT2, or factors that affect the ability of ZnT2 to function properly. 

According to the research, the lactation process may go haywire when a mother is overweight or obese.Two-thirds of women of reproductive age in the U.S. are overweight or obese and these women tend to have difficulties initiating and maintaining lactation. 

Researchers are investigating the possibility that zinc and ZnT2 might have something to do with this.  

How long should I breastfeed?

The World Health Organization and American Academy of Pediatrics recommend exclusive breastfeeding through 6 months of age, but only about 14% of women meet this goal.

Why breastfeed?

Other than helping the baby to grow and develop there is some evidence that breastfeeding improves immune function and cognitive development in babies, and also reduces their risk of diabetes, obesity, and cardiovascular disease when they become adults.

How long do the strips last after the bottles is opened?

Strips are good for 90 days after opened.
