Results Reported

Typically, for positive, quantitative reports ≤ 5 business days TAT from receipt.

Acceptable Matrices

Whole Blood; 1 x 4 mL Sodium Fluoride (grey top; preferred) or EDTA (purple top) tubes. Any non-retrievable specimen will be considered.

Causes for Rejection

• Identifiers on the specimen DO NOT match, when compared with the requisition.
• Specimen handling has compromised the integrity of the specimen (e.g., not stored, or prepared according to testing requirements; frozen specimens and specimens fixed/processed in alternative fixatives)
• Specimen quality is compromised at or beyond ability to complete testing and provide accurate results (i.e., quality not sufficient [QNS]).
• Serum-separated specimens.
