I know that this issue was discussed many times. But in most cases it was with other instruments than Dade (I should say Seimens) RxL. We had a case where the first Trop I was 0.6 ng/ml. The patient was hospitalised and the result repeated according to our protocol 6h later, the second result was 0.1 ng/ml. I received the call from the ER physician. I asked to centrifuge the first specimen at high speed. The result came down to 0.1 ng/ml. It's well known that the integrity of the specimen can affect the result. My question is :
Should we centrifuge at high speed all the specimens for troponin I? (it,s not recommanded by the manufacturer).
Thanks ahead for your input
