The 547L
Heparin Level / Anti-Xa assay quantitates the plasma level
of heparin for purposes of managing the patient’s therapy.
The laboratory uses the same type of heparin or hepranoid
that the patient is receiving for calibration of the assay.
The types currently used are unfractionated, Lovenox,
Fragmin, and Orgaran.
Effective
1/14/02, we will report the type of heparin used for testing
so that the physician will have this information in the
patient’s record.
Please
help us provide the quickest and most accurate results by
always marking the heparin type on the test requisition. If
you are unable to determine the heparin type, the laboratory
will use unfractionated porcine heparin for testing.
If you
have any questions or concerns, please call client services
at
1-(800) 967-9672 or
(412) 209-7270.
Thank you
for choosing our laboratory.
