Sample passes for water activity (sample fails if Aw>0.65). Water activity is measured utilizing SOP FE-45 (water activity meter).

LOQ = Limit of Quantitation; %RPD = Relative Percent Deviation; %RSD = Relative Standard Deviation; N/D = Not Detected

*Designates values that are not currently included in the accredited scope of Iron Laboratories.

*** Designates tests that use the method FE-45. FE-45 is performed using AOAC 966.02 and 32.004-32.009.

FE-45 has relative expanded (k=2) uncertainties of 1.098% for moisture, 1.754% for water activity for unprocessed plant materials, and 13.102% for water activity for infused products.

Vitamin E acetate analysis has a relative expanded (k=2) uncertainty of 18.614%.

Total THC and CBD is the calculated sum of Δ9-THC and Δ8-THC or CBD plus the amount of THC or CBD derived from THCA or CBDA, respectively.

These values are calculated by applying a molar correction factor of 0.877 to the THCA or the CBDA value.

Calc Max Total Cannabinoids is the sum of Total THC, Total CBD, CBN, Total CBG, CBC, THCV, CBDV, and CBL.

Total CBG is calculated as CBG plus CBGA*0.878 (the molar correction factor for CBGA to CBG conversion).

%Decarb. THC and CBD refer to the percentage of Δ9-THC or CBD relative to THCA or CBDA, respectively.

Sample was sampled and tested in accordance with the Safety Compliance Facility Sampling and Testing Information.

LR = indicates compound recovery of matrix spike was outside the methods acceptable limits. (70-130%) Low recovery should be scrutinized for possible fail as it could indicate more compound present than is detected.

I = indicates that an amount of an interfering compound greater than the methods limit of detection was detected in the method blank sample. May indicate contamination of analytical system or consumables.

Q = indicates that the relative percent diference of two identicly prepared Matrix Spike samples for a target analyte was greater than 20%

HR = indicates compound recovery of matrix spike was outside the methods acceptable limits. (70-130%) high recoveries should be scrutinized for passing as more compound may be detected than is actually present in the sample.

Q = indicates that the relative percent diference of two identicly prepared Matrix Spike samples for a target analyte was greater than 30%

R = indicates compound recovery of matrix spike was outside the methods acceptable limits. (60-120%) Low recovery could indicate there is actually more compound present than detected; while high recoveries should be scrutinized for possible fails as more compound may be detected than is actually residual on the sample.

E. coli test screens exclusively for Shiga toxin-producing E. coli. TNTC values for yeast and mold are >150,000 CFU/g. TNTC values for total coliforms are >15,000 CFU/g. The maximum relative uncertainty is 6% for PCR and 40% for MPN.

TNTC = Too Numerous To Count. Maximum Colony Forming Units (MCFU) represents the minimum value that a test would need to achieve in order to be considered a failed result (if applicable). LOD is the Limit of Detection for the method. CFU/g = Colony Forming Units per gram. Aspergillus spp. consists of A. flavus, A. fumigatus, A. niger, and A. terreus.

Sample was sampled and tested in accordance with the Safety Compliance Facility Sampling and Testing Information.
