|Downtime form:||A-1a Doctor/Provider Orders - Pathology Core and Specialty Care Nursery|
|Plasma Separator Tube 4.5 mL|
Toxic concentration > 60 μg/mL
Coma without reflexes may occur at concentrations > 100 μg/mL.
Hemolysis: No significant interference up to an H index of 1000 (approximate hemoglobin concentration: 1000 mg/dL).
Lipemia (Intralipid): No significant interference up to an L index of 600 (approximate triglyceride concentration: 1200 mg/dL). There is poor correlation between turbidity and triglycerides concentration.
Rheumatoid factor: No significant interference up to a concentration of 200 IU/mL.
Mephobarbital (greater than 100%) and amobarbital (greater than 20%) show significant cross-reactivity.
As with any assay employing mouse antibodies, the possibility exists for interference by human anti-mouse antibodies (HAMA) in the sample, which could cause falsely elevated results.
