Temperature Period
Room temperature: 29 days
Refrigerated: 29 days
Frozen: 49 days
Freeze/thaw cycles: Stable x5
Cause for Rejection:
Citrate: Boric Acid used as a preservative (Boric acid >=1250 mg/dL may cause citrate results to be reduced by approximately 30%); Multivitamin >=397.5 mg/dL (estimated as 1 pill per day) may cause citrate results to be unmeasureable. Results of interference testing may not be representative of in-vivo characteristics of multivitamin consumption.
