Sam Spade my 14 yo had bloodwork done in June and again last week. Some of the results seem wacky.     He has also lost 2 pounds since January from 9 to 7 pounds.
I am concerned about the weight thing. I was going to have a free T 4 done ($200 as an add on now later $230 or more).

Platelet count
June     700
Nov      184


June     2842
Nov      1377


June     392
Nov      162


June     98
Nov      243

Does that seem strange to anyone?

Yes it does seem strange . Didn't they say anything about the dramatic change ?

It is impossible to know if these lab results are strange or not without the reference ranges.  These values can change for any number of reasons, but if they are within the reference range, they are fine.  The Platelet count can be low due to clumping of the platelets and the machine cannot do an accurate count.  Usually there would be a note on the report saying that "platelets are clumped" or something like that, and also that platelets are "adequate".  

The lymphocytes, eosinophils, and monocytes, which you listed, as well as the neutrophils, which you did not list, are called the Differentials of the white cell count.  They actually total the White Blood Cell count (WBC).  If the WBC is within the normal reference range, there is probably not any big problem.  However, one or more of the differentials can be out of whack for various reasons, but it is usually not a problem unless they are out of that normal reference range.  If you can give more information, I will see if I see any specific problem.  

You do not need a Free T4.  If your concern is the weight loss and possibility of hyperthyroidism, it is a T4 (also referred to as Total T4) that you would want to have done.  The Free T4 is not used to diagnosis hyper-t.  In fact, it very often only confuses the issue when it is slightly above normal and the T4 is normal.  The Free T4 can be elevated for other reasons.  I don't see that you listed a T4, but if you had that done, post the result.  In the past, it was thought that an elevated Free T4 along with an elevated T4 or a T4 in the upper end of the reference range was diagnostic for hyper-t.  That has changed with research.  The Free T4 is no longer relied upon to confirm hyper-t, especially when the T4 is not elevated above the reference range, and the cat has other non-thyroidal medical issues.

Agree on the T4 and not needing a free T4.  (Also, $200 for a free T4 when I can get a five panel thyroid through Hemopet for $100 seems like highway robbery.)

Was there other bloodwork done?
