The link takes you to a page where you can download a Request Form or Dr. Holland's technical brief on "Canine Ehrlichiosis and Diagnostic Importance of End-Point Titers".
The drop-down menu under Reference Lab takes you to information about Dr. Holland, the services ProtaTek offers and testimonials from vets who use their laboratory.

IFA tests for E. equi (A. phagocytophilum) and E. risticii (N. risticii) can be requested as add-ons to the basic tick panel.

Protatek is the laboratory we recommend most on Tick List. They are accurate, turnaround time is fast if the sample is gotten to them at the beginning of the week, and Dr. Holland is very helpful and willing to discuss test results if you have any questions.

How Do You Know Treatment Is Working?
"You'll probably notice some pretty obvious improvement yourself when your dog stops limping so badly, say, or seems to have regained his enthusiasm for life.  Then six months, eight months,
a year after treatment for TBD, when antibody levels have had time enough to fall, you'll want to do another specialized test to see if the disease really has been arrested. Between now and then,
though, keep in mind that your own vet is in the best position to determine how well your dog is responding to treatment, both while it's underway and in the time period when you have to wait
and will those antibodies down.

"With all these diseases the most useful criteria for assessing the success of treatment in the short run are clinical symptoms and routine clinical pathology lab results rather than specific TBD testing."
