Special Info

Patient preparation: Preferably fasting for 12 hours or more. Patients taking a Biotin dose of up to 5 mg/day should refrain from taking Biotin for 4 days prior to sample collection. Patients taking a Biotin dose > 5 mg/day to 10 mg/day should refrain from taking Biotin for 7 days prior to sample collection. Patients taking a Biotin dose > 10 mg/day should consult with their physician or the laboratory prior to having a sample taken. Clinicians should consider biotin interference as a source of error, when clinically suspicious of the laboratory result. The Gastrin test was performed using the Siemens Immulite chemiluminescent immunometric method. Results obtained with different assay methods or kits cannot be used interchangeably.

Clinical Info

For diagnostic purposes, the results obtained should always be used in combination with the clinical exam, patient medical history, and other findings.

Clinical Limitation

Lipemic,icteric or grossly contaminated samples may give erroneous results. Hemolyzed samples may indicate mistreatment of a specimen before receipt in the laboratory; hence the results should be interpreted with caution.
