Guest guest Posted June 12, 2010 Report Share Posted June 12, 2010 Hi guys, Can anyone here help me with a math formula for calculating mid-ranges in labs? I am really bad at math and find this very math-challenging, but important to know where my labs are with FT3 and Ft4. My Free T4 is 1.2 with lab range of (0.7-2.0) What math formula do I use to find the mid range---I can only " guesstimate " that it is a little below mid-range. Thanks!
