Sorry, we aren't taking any more orders this week.
We are working on ways to expand our testing as well a few other projects. We have reduced the number of orders we take each week to make sure we have some time to make these improvements. These limits should be temporary! In a few months we will take off the brakes.
We will take more orders next week. Orders open on Monday, Sydney time. In the mean time, have a look through our individual tests and panels (panels are groups of tests) to help decide what you want to test for.
Malignant hyperthermia (MH)
Summary
Malignant hyperthermia (MH) is one of the 5 tests in the 5-panel. The 5-panel is relevant to Quarter Horses, Paints, Appaloosas, Quarter Ponies and any other breeds with some Quarter Horse bloodlines.
Malignant hyperthermia is overheating, rather than hypothermia which is getting too cold. It happens when muscle cells leak calcium under anaesthetic, triggering a rapid increase in body temperature, high heartrate and other problems. Left untreated, malignant hyperthermia can be lethal. Malignant hyperthermia in horses is rare, and is only caused by the use of halothane (inhaled) anaesthetics.
If your horse tests positive for the MH gene, inform your veterinarian. They will need to know before undertaking surgery or other treatments that require anaesthesia.
