LIMITATIONS
Test results of the HEMOCHRON Signature Elite Microcoagulation instrument are affected by poor technique
during blood collection and delivery to the sample well. The accuracy of the test is largely dependent upon the
quality of the blood specimen, which is dependent upon the blood sample collection and the transfer of blood to
the test cuvette. Refer to the individual assay package insert for specific limitations.
HEMOCHRON Signature Elite test results should always be scrutinized in light of a specific patient’s condition
or anticoagulant therapy. Any test results exhibiting inconsistency with the patient’s clinical status should be
repeated or supplemented with additional diagnostic tests. Samples with a hematocrit less than 20% or greater
than 55% are not recommended, due to an optical density outside the detection level of the HEMOCHRON
Signature Elite Microcoagulation instrument.
RESULTS MANAGEMENT
Up to 600 patient test results and 600 quality control test results can be stored in the instrument. In addition to
test results, the date and time of each test, PID, OID, and user notes are also stored.
Note: PID and/or OID are not stored if a value is not entered when the test is run. A PID is not
allowed for any QC test.
Note: If an error is encountered with the test or the sample, the error message for the error will be
included on the printout. Refer to page 75 for error messages, their cause, and their resolution.
