Alertys pregnancy tests

Establish a protocol for reproductive efficiency with superior accuracy.

  • Reduce days open, increase production, and improve herd health with accurate, fast results.
  • Confirm results with pregnancy-associated glycoproteins (PAGs), which are only produced in the presence of an embryo or fetus.
  • Alertys milk- and blood-based tests offer flexible testing options with results as early as 28 days postbreeding.

Why use sample-based testing?

Use milk or blood samples to know if your cows or heifers are pregnant.

Alertys pregnancy tests use blood and milk samples to detect pregnancy-associated glycoproteins (PAGs), which are only produced in the presence of an embryo or fetus.

Assess overall herd health

An open pregnancy result can suggest the presence of disease.

Frequently asked questions

  1. Label tube prior to sampling. Include date and individual cow ID. It is essential to ensure that the correct tube is used for the correct animal. Failure to do so may result in an incorrect status being assigned to the cow.
  2. Using the wet wipes or towel, remove dirt and detritus from the teats. Ensure udder is clean and dry prior to starting sample collection.
  3. Samples may be taken from individual quarters or as a composite sample of all four quarters.
  4. Discard a few streams of milk and remove the cap from the tube or vial. Angle tube at 45º to the teat end.
  5. Fill the tube or vial three-quarters full from one or multiple quarters and replace the cap.
  6. Place samples in a refrigerator prior to shipping to the laboratory.
  7. Samples should be well-packaged and kept cool during shipping (especially if preservative has not been used).
  1. Restrain the cow; clean the underside of the cow’s tail with a paper towel.
  2. Lift the cow’s tail straight up and measure up about 2 inches (7.5 cm) from the base of the tail, staying within the groove between the two bony ridges. This is the collection site. 
  3. Insert the external needle into the underside of the tail, at the collection site, about 1/2 inch deep, keeping the needle perpendicular to the tail. 
    IMPORTANT: The external needle must be perpendicular to the tail. Do not angle the needle up, down, or to the side. 
  4. Push the tube in gently until the internal needle punctures the tube stopper. The vacuum will draw the blood into the tube. Note: If no blood appears, pull the external needle back slightly (without withdrawing it from the skin), and reinsert it in a different direction until you puncture the vein.
  5. When the tube is at least half full, withdraw the needle from the vein and remove the tube from the needle holder.
  6. Discard the needle and yellow/gray caps into a sharps container. The needle holder can be reused if undamaged. 
  7. Make sure the tube label is clean and dry; label the tube with the sample number and the cow ID.
