Guest JoyceJ Posted August 1, 2008 Share Posted August 1, 2008 (edited) Did routine labwork (IDEXX) in preparation for our nine year old, 80# male's dental. If I had suspected any possible thyroid problem, I would have asked that the bloodwork be sent to MSU. This boy exhibits NO signs of hypothyroidism. BUT. his Free T-4-e.d. (ng/dl) came back at 0.5....IDEXX reference range 0.7-2.5 ng/dl his Free T-4-e.d. (pmol/L) came back at 6.4....IDEXX reference range 9.0-32.2 pmol/L, his T-4 came back at 0.4 ..IDEXX reference range 1.0-4.7 ug/dl and his cTSH was 0.54. ..IDEXX reference range 0.05-0.42 ng/ml I'm looking for the most current "greyhound normal" ranges for T-4, fT4 and cTSH for comparison. Since he appears to have low free T4 by dialysis, a low total T4 and a high TSH (even for a greyhound), is there a reason I would want MSU to redo this same bloodwork? Also, would it make sense (based on his numbers and his weight) to start him at 0.6 Soloxine for the first 30 days and then readjust after labwork? Thanks in advance.!!
