Our hospital system is seeing all sorts of aberrant results in GEL recently: mixed field reactions in multiple microtubes, Positive screening cells, with negative IDs, results inconsistent with patient history, results not reproducible, on and on........... Ortho is defending their product MTS Gel, but the evidence is mounting against this system as being far too sensitive and unreliable. While my colleagues in this e-forum have suggested multiple backup plans and methods for dealing with the GEL results, to keep retesting over and over is not feasible and too costly in terms of TAT and efficiency in the deparment. We find ourselves having to retest far too many patients and, as supervisor, I am flooded with calls, inquiries, and "what to dos" If these large blood centers are jumping ship and going back to tube testing, there should be a message loud and clear to Ortho embedded in there. While this is being sorted out, give me a supply of 12 x 75s and a marking pen. Dr Stephen Bright St Elizabeth Regional Health Lafayette Indiana
