You have an cTNI result of 45.0 ng/mL.  That AMR and Assay Range is 0.017-40.00ng/mL. The CRR is 0.017-200.00 ng/mL. Your instrument flags as “ABOVE ASSAY RANGE”.  What are your next steps in resulting the patient results?

Report the 45.0 ng/mL result.

Dilute the sample with enzyme diluent and rerun the sample. Report the new result as it falls within the CRR.

Dilute the sample with CTNI sample dilute and rerun sample.  Report the new result as it falls within the CRR.

Call the nurse immediately with the critical value.

Dilute the sample with CTNI sample dilute and rerun sample.  Report the new result as it falls within the CRR.

Brandon is running a manual body fluid.  She takes out a Level One and Level Two of Streck Cell-Chex body fluid controls on 04/08/2018 and puts it back in the refrigerator.  On May 3, 2018 Mayur wants to use the sample controls.  Can he use the controls?

No, the QC is only good for 15 days after opening.

No the QC should be left at room temperature.

Yes, the QC is good for 30 as long as it is refrigerated.

Yes, the QC is good for 60 days as long as it is refrigerated.


Yes, the QC is good for 30 as long as it is refrigerated.

The doctor ordered a ANTI-XA test at 0830 for a patient on heparin therapy.  Natasha notices that she drew the sample at 0600. Can the ANTI-XA  be added to the draw. Should it be added to the draw?

Yes. The sample is within the 4 hour window for PTT samples.

No. The sample should not be added on because the clinical outcome of the patient will be adversely affected due to inaccurate Anti-Xa result because of the collection time of the sample. 

No. The sample should not be added on because the clinical outcome of the patient will be adversely affected due to inaccurate Anti-Xa result because of the collection time of the sample.

  1. Juliana gets all [*] on the differential. She notices that a diff was done within 72 hours and the current automated results agree with the previous differential.  What should be here next step?
    1. The differentials agree and no diff is needed.
    2. Per policy the differential was done with in the last 72 hours. So a differential is not needed.
    3. The flag indicates low reliability and the differential should be performed.
    4. The flag indicates the results are out of range and the differential should be performed.

The flag indicates low reliability and the differential should be performed.
