HOW IT WORKS Results Interpretation

Normal patient:

Result Interpretation

Normal patient:
For each of the ROTEM® assays, a normal patient will exhibit a TEMogram within the reference range for each reagent.
Please note: Results from the ROTEM®delta should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient's medical history, the clinical picture and if necessary, further coagulation tests.

Platelet deficiency:


platelet_deficiency



Platelet deficiency:
In this case, all CT's and CFT's are within the reference ranges.  MCF's for in-tem®, ex-tem®, and ap-tem®are all below the reference range, suggesting a deficiency in either platelet function (due to insufficient platelets or impaired function) or fibrin polymerization or fibrinogen.
The fib-tem®assay MCF is within the reference range, suggesting that fibrin polymerization or fibrinogen is normal, further suggesting insufficient platelets or impaired platelet function.
Please note: Results from the ROTEM®delta should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient's medical history, the clinical picture and if necessary, further coagulation tests.

Fibrinogen deficiency:

 Fibrinogen deficiency:
In this case, all CT's and CFT's are within the reference ranges. MCF's for in-tem®, ex-tem®, and ap-tem® are all below the reference range, suggesting a deficiency in either platelet function (due to insufficient platelets or impaired function) or fibrin polymerization or fibrinogen. The fib-tem®assay MCF is below the reference range, suggesting this patient has a deficiency in fibrin polymeriztion or fibrinogen.
Please note: Results from the ROTEM®delta should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient's medical history, the clinical picture and if necessary, further coagulation tests.

Hyperfibrinolysis:

Hyperfibrinolysis:
The abnormal level of ML at 30 minutes in the in-tem®, ex-tem® and ap-tem® tests suggests fibrinolysis.
In comparing ap-tem® parameters to those of ex-tem®, the ap-tem® parameters CT, CFT, and MCF return to the reference range for ex-tem®, further suggesting fibrinolysis.
Please note: Results from the ROTEM®delta should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient's medical history, the clinical picture and if necessary, further coagulation tests.

Heparin influence:

Heparin influence:
The prolonged CT in the in-tem® test is significantly shortened in the hep-tem® test, to a value within the in-tem® reference range. Also, CFT and MCF parameters return to reference range values. This comparison of hep-tem® results to in-tem® results suggests that the sample contains unfractionated heparin.
Please note: Results from the ROTEM®delta should not be the sole basis for a patient diagnosis, but should be evaluated together with the patient's medical history, the clinical picture and if necessary, further coagulation tests.
