Comparison lab values

by Lolly43, Jul 23, 2009 09:27AM
I have been being monitored for a IgG lambda M spike in the beta globulins since May '08.  All blood tests have been sent to the same lab, and I have been being monitored every 3-6 months.  In Jan. '09 my spike increased to 0.8 from baseline of 0.6.  I was just re-tested after 6 mths. and spike now at 1.2.  My doctor decided to repeat test to make sure it wasn't a false spike before putting me through another bone marrow, etc.  that sample was drawn at a different lab and subsequently sent off to another lab for analyzing.  The result came back 0.8.  It seems to me that if you are double checking a lab value, you would send it to the same lab for the repeat.  Otherwise, I don't think you're comparing apples to apples.  Am I wrong about this, and now that I have 2 greatly different lab values, how do you decide which one is the accurate on?  Seems like another test needs to be sent to the original lab for re-testing.

I agree with you. The same lab should be used.
