Bionote USA Debuts New One-Step, Rapid Canine Heartworm Test

No Buffer Required for Standalone Antigen Test That Detects Heartworm

BIG LAKE, MINN. (June 5, 2024)  Bionote USA has added a new one-step rapid test for the detection of Canine Heartworm (CHW) to its line of in-clinic diagnostic products. The standalone antigen test requires no analyzer or buffer solution, and results are ready in minutes. Bionote USA brings a variety of in-clinic diagnostic analyzers and quantitative biomarker tests to the North American veterinary market, including its flagship Vcheck analyzer.


After collecting a sample, veterinarians or technicians simply add two drops of serum, plasma or whole blood to the sample hole in the CHW testing device and wait 5-10 minutes for results to be indicated. Bionote’s CHW test has been shown to be exceptionally effective through a university-validated study indicating 94.4 percent sensitivity and 100 percent specificity in both symptomatic and asymptomatic dogs. The American Heartworm Society recommends year-round prevention and annual antigen and microfilaria testing.


“Offering this new, streamlined and validated option to the veterinary marketplace can help save staff resources and time in-clinic while screening canines for this life-threatening infection,” said Randy Knick, president of Bionote USA.


Available for order in boxes of 10 or 100 test kits, Bionote’s CHW rapid test provides positive or negative results for heartworm detection. CHW’s testing methodology detects Canine Dirofilaria immitis antigen in the sample. Antigen testing has proven to be the most sensitive method for diagnosing heartworm presence, with positive results occurring within 5-6 months of the initial infection.
