We were asked today what a ‘trace’ value on the leukocyte reading could mean when all the other parameters on the test are negative. Generally, trace values on any of the parameters of the urine test strip should be repeated within the week.
If an infection is present, the leukocyte value will usually be higher (you will get a ‘moderate’ or ‘large’ reading) and the nitrite value will also be positive.
A trace value in this case means that the body is having an immune response to something. It could be one of many things and also very short-lived.
This is good information to know. Record the reading on the results chart so you will have this information to refer to and also to report to your veterinarian during any future visits.
