Thanks Chip, I can see if they will accept the titer test in court. May be tough but we'll see if it gets to that.
The DM test, if I recall was around $200 or so. But it was back in 2012 so my memory on it may be a bit hazy as it cost me $2,000+ before they even got to that test. (Xray's, multiple Dr. visit's, etc.)
