Limulus Amebocyte Lysate (Endotoxin)
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
If additional specimen dilutions are required to obtain an accurate result, up to 3 additional dilutions could be performed, each at an additional charge.
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
LEVEL DETECTED INTERPRETATION
<0.05 EU/mL None Detected
0.125 EU/mL Action level for dialysis water
<0.25 EU/mL Maximum allowable level for dialysis water and USP acceptable limits for injectable or irrigation water
0.25 EU/mL Action level for dialysis fluid
<0.50 EU/mL Maximum allowable level for dialysis fluid and USP acceptable limits for inhalatory water.
2.00 EU/mL Acceptable upper limit for Hemodialysis reuse water.
The LAL is used as a quantitative test to detect gram-negative endotoxin in aqueous solutions used in patient management. The LAL assay is not recommended for serum or plasma samples due to the presence of inhibitory factors. It is essential to maintain specimen sterility and prevent false positive results from exogenous gram negative bacteria.
