No Dogs Allowed: Quality Testing Guarantee

No Dogs Allowed: Quality Testing Guarantee

Have you ever wondered what goes on in a genetic testing laboratory? What kinds of measures are taken to guarantee quality testing? For example, does the laboratory that you use have what is pictured - a clean room? What is a clean room and why should they have one? And why can’t you bring your dog directly to the laboratory for swabbing?

Paw Print Genetics has received a lot of questions about our testing quality and accuracy – and we love it! Ask away! We like to talk about our lab and the careful approach we take to testing to ensure that your results are reliable and accurate. Otherwise, what’s the point?

A genetic testing lab must have accurate and reliable results. They should have performed validation studies for each of the diseases and mutations that they offer. Does your testing lab provide you with the test’s sensitivity and specificity for the diseases you are concerned about? Have you asked for this?

During our validation studies, we assessed eight performance criteria for each test: accuracy, precision, analytical specificity, analytical sensitivity, detection limits, reportable ranges, reference intervals and robustness. For example, accuracy refers to getting the right results; whereas, precision refers to ...

Do English cocker spaniels share any diseases in common with people?

Do English cocker spaniels share any diseases in common with people?

               When you are a veterinarian living in a swirling haze of disease prevention and treatment, you often forget that most people don’t spend their spare time thinking about disease processes on a regular basis. They are even less likely to spend time comparing canine diseases to illness found in them or in people they know. Therefore, I suppose I shouldn’t be surprised when my friends, family and clients find it so fascinating and unbelievable when I tell them that dogs inherit and develop many of the same genetic diseases as people.  In fact, dogs are well recognized in the scientific community as terrific models for particular diseases in people and have been thoroughly studied to gain information on many conditions. According to the Online Mendelian Inheritance in Animals (OMIA; http://omia.angis.org.au), as of this writing, there are 343 genetic mutations identified in dogs that are considered to be “potential models for human disease” and the list continues to grow rapidly since mapping of the full canine genome was completed in 2005.  The mapped genome of a boxer named Tasha provided a much needed framework for genetic comparison studies ...
