Reference Range: |

Comments: |
Patient must have fasted for 12 hours. Please print, complete and submit the Advance Beneficiary Notice (ABN) along with the Laboratory Requisition before shipping the specimen. | ||
Test Limitations: |
Serum/Plasma Icterus: Significant negative interference at an I index of greater than 25 and greater than 15 (approximate conjugated and unconjugated bilirubin concentration: 25 and 15 mg/dL). Hemolysis: No significant interference up to an H index of 400 (approximate hemoglobin concentration: 400 mg/dL). Lipemia (Intralipid): The L index correlates with sample turbidity and not to triglycerides level. Serum samples having extremely elevated triglycerides (greater than 3000 mg/dL) are underestimated by the Triglycerides/GB methodology and could produce a normal result on an elevated sample.* Prior to being tested for triglycerides, dilute grossly lipemic sera 1 part serum to 4 parts 0.9% NaCl and multiply the results by 5. For the 911, 912 and 917 analyzers, run with decreased samplevolume. Not all samples having this level of triglycerides are grossly lipemic. *Shephard MDS, Whiting MJ.
