Why not use traditional genotyping?

Both methods identify A2A2 animals. The difference is how long it takes, how much it costs and who can do it.

Frequently asked questions

Still have questions?

The most common questions from people about to test their herd. See them all on the FAQ page.

How does the test work in practice?
You collect a few drops of milk from the animal in a clean, dry vial, apply the sample to the MilkTest® device (similar in format to a pregnancy test) and wait 20 minutes. Two lines — control and test — indicate A2 milk. A single line indicates it is not A2. No equipment or licensed professional is required.
Is the test accurate? What is its accuracy?
Yes. MilkTest® was validated against genotyping, the gold-standard method, showing 100% sensitivity and 100% specificity for identifying A2A2 animals. It is a reliable screening test for use in the field.
Where can I buy MilkTest®?
On this page you can build your order with the quantity you want and complete the purchase through the Dairy Tech sales WhatsApp (+55 49 99973-4733), where our team confirms shipping and payment method.
Does the test need to be refrigerated?
No. MilkTest® is stored at room temperature, with no need for refrigeration, which makes it easier to transport and use on the farm.
What is the difference between MilkTest® A2 Milk and PureMilk?
MilkTest® A2 Milk identifies whether an animal is A2A2, using the milk of a single animal — ideal for screening the herd. PureMilk checks the purity of A2 milk in a tank or pooled milk, detecting A1 beta-casein contamination — ideal for dairy processors and cooperatives that need to ensure the purity of the milk they bottle.
How many tests do I need for my herd?
Each MilkTest® A2 Milk test analyzes the milk of one animal. To screen your herd, you need one test per cow you want to check. Tests are sold in packs of 1, 3, 10, 15, 30, 50 and 100 units — the larger the quantity, the better the terms. If you are unsure about the right volume, talk to our sales team.
