mollyredone Posted September 27, 2014 Share Posted September 27, 2014 We have an 11 month old with TAR syndrome who is being transfused regularly with plateletpheresis. When she was first born we didn't perform a back type. But a couple of months ago I started to think we should do one, as she should have formed antibodies at about 6 months. But her backtype is not positive unless it is incubated at 4 degrees (with a control of course) for 15 minutes. Does anyone know if this is a symptom associated with TAR? Thanks!

L106 Posted September 29, 2014 Share Posted September 29, 2014 (edited) We had such a patient and never had any problems with her ABO reverse grouping. Donna Edited September 29, 2014 by L106 Link to comment Share on other sites More sharing options...
John C. Staley Posted September 29, 2014 Share Posted September 29, 2014 Old guy here, out of touch for a few years. What is TAR syndrome? Link to comment Share on other sites More sharing options...
L106 Posted September 29, 2014 Share Posted September 29, 2014 TAR = Thrombocytopenia-absent radius syndrome The child has lacking the radius bone in each forearm and they have a low platelet count. TAR Syndrome is also often associated with other skeletal, hearth & kidney malformations. Our patient took numerous platelet transfusions (and occasional red cell transfusions) during her 5 years of life before she passed away from an infection not directly related to her TARS.

Dr. Pepper Posted September 30, 2014 Share Posted September 30, 2014 Mari, I'm guessing that the child is just coincidently a little late in developing the antibodies. They seem to be there, just not in a very high titer yet. The tech manual says "as early as age 3-6 months, with nearly all....at 1 year." She's within this range.
