Serous body fluid (pleural, peritoneal and pericardial) specimens received in an EDTA tube are preferred.
Other sources, containers or anticoagulants are suitable provided the sample is free from clots and/or debris.  
Room temperature. Refrigerate if greater than 2 hours before testing.

Link to ARUP Test Directory (Opens in a new window) for the SRA confirmation reflex test.

Turnaround Time:

Routine: 2 Hours
Urgent: 1 Hour

Test Schedule:

Batched daily 7 days per week. Please call 503-494-5764 if STAT.

Critical Values:

Preliminary Positive, Confirmation Pending

Specimen Requirements:

One 2.7 mL Lt Blue Na Citrate tube and one 5 mL Gold SST tube.

Pediatric Specimen Requirements:

One 1.3 mL Lt Blue Na Citrate tube and two pediatric red top tubes.

Reference Range:

HIT Ab Negative

Comments:

Method: Immunoturbidimetric detection of anti-PF4/Heparin (PF4/H) antibodies.

Interferences:
The HIT Ab assay is not affected by hemoglobin up to 500 mg/dL, bilirubin up to 19 mg/dL, triglycerides up to 375 mg/dL, rheumatoid factor up to 100 IU/mL and human anti-mouse antibodies (HAMA) up to 1 microgram/mL.

No dose-response correlation between HIT results and heparin concentrations was shown in manufacturer studies; UFH (n=11) range from 0.04-1.08 IU/mL and LMWH (n=115) range from 0-2.47 IU/mL).

Testing on 40 samples from patients diagnosed with Antiphospholipid Syndrome (APS) showed no HIT Ab positive results indicating that the assay is not affected by APS antibodies.

Turnaround Time:

Units:

micromoles/L

Specimen Requirements:

4 mL of blood in a RED top tube. Avoid exposure to light.

Reference Range:

Therapeutic Range
Low dose: 0.5 to 1.0 micromoles/L
High dose, 24 hours: Less than or equal to 5.0 micromoles/L
High dose, 48 hours: Less than or equal to 0.5 micromoles/L
High dose, 72 hours: Less than or equal to 0.10 micromoles/L

Comments:

This assay shows cross reactivity with DAMPA (2,4-Diamino-N10-methylpteroic acid). 
Specimens from patients who have received glucarpidase (carboxypeptidase G2) as a high dose methotrexate rescue therapy should not be tested with the EMIT Methotrexate assay. These specimens have increased serum levels of metabolite (DAMPA) that cross-reacts with the methotrexate antibody used in the assay.
