D2Dx™ Immunity Test 

  One-Minute Blood Test for Animal Immune Health Testing

About Us

Nano Discovery Inc. is a biotechnology company based in Orlando, Florida, United States. We develop, manufacture and sell a rapid blood test product, D2Dx™ immunity test, to detect and monitor the immune status and health of farm and companion animals.  D2Dx™ technology is protected by multiple granted patents and pending patent applications.

TECHNOLOGY

D2Dx™ immunity test is a rapid blood test for animal immune health testing.  It is a one-of-its-kind test that allows quick and accurate assessment of an animal's immune status in the farm, at the animal side. Farmers and veterinarians can conduct the test in their own local facilities without the need of shipping samples to laboratories and waiting for days to receive the results. Our product is built upon and supported by years of research and extensive data evidence. We are proud to provide satisfaction guarantee to our clients and customers. READ MORE

Dairy Cows - Better Immunity, Lower Disease Risk and Better Fertility

Dairy cows experience many health challenges during the transition period. Immune health plays a critical role in protecting dairy cows from infectious diseases. Studies show that D2Dx™ immunity test can monitor the immune status change of dairy cows during the periparturient period. The test can identify cows with high immunity and reduced risk of developing metritis post calving.


Getting a dairy cow pregnant on time remains a significant challenge in dairy industry.  Reproduction is closely related to immune health and immune status in the animal. Recent studies found that D2Dx™ immunity test can help identify cows with higher pregnancy probability from cows with lower fertility. Cows identified by D2Dx™ immunity test as high immunity group had a conception rate of 60-75%, while cows identified by the test as low immunity group had pregnancy rates around 30%. Cows with extremely low immunity scores failed to become pregnant after multiple AI services. 

Calves - Better Immunity, Better Health and Feed Efficiency

D2Dx™ immunity test has been used to monitor the immune status and immunity development in newborn calves, neonatal calves and newly weaned feedlot calves. On dairy calves, the test has been used to monitor immunity transfer from mother cows to calves through colostrum feed. There is a strong positive correlation between  D2Dx™ immunity test and total serum protein (TSP) test. D2Dx™ immunity test adds another convenient tool for dairy calf health management.


Studies also found that calves that can develop higher immunity scores within the first few weeks following birth show higher average daily weight gain. Other studies show that the test can detect significantly compromised immune function in feedlot calves caused by transportation, stress and infection. The test may be used in feedlot to reduce the use of antibiotic treatment on feeder calves. Feedlot calves with higher immunity scores were found to have better feed efficiency.

Sheep and Lamb - Better Immunity, Lower Fecal Egg Count (FEC)

D2Dx™ immunity test has been used to monitor the immune status and health in ewes and lambs. Studies have found that ewes with higher D2Dx™ immunity test scores tend to have less risk of parasitic infection (lower FEC) and lower somatic cell count (LogSCC) in milk compared to ewes with low immunity scores. Lambs that can develop better immunity within the first few weeks following birth also tend to have lower FEC.


D2Dx™ immunity test may also be used to identify mother ewes with better immune health for selective breeding. Researchers found a positive correlation between mother ewes' immunity scores during peri-parturient period and the general health of newborn lambs. Lambs born from mother ewes with higher immunity scores tend to have higher immunity scores and show higher average daily gains in the first 60 days following birth.

Using  D2Dx™ Immunity Test for Feed and Nutrition Plan Management

Feed and nutritional supplements are extremely important for animal health. Animals require different types and levels of nutrition supply at different growth stage. The nutrition needs of farm animals also vary according to seasons and their geological locations. There are many feed, nutrition and supplement products in the market that are formulated to improve the immune health of the animals.


D2Dx™ immunity test provide a simple solution for farm owners, managers and veterinarians to monitor the immune health of entire herd conveniently on farm setting. Based on the results, feed and nutrition plans may be adjusted to achieve the best results. Use D2Dx™ immunity test to make informed and timely management decisions.
