Methodology

Ultra-High-Pressure Liquid Chromatography (UHPLC) coupled to Triple Quadrupole tandem Mass Spectrometry (QqQ MS/MS).

Assay Availability

Screening for this assay is setup Mon., Wed., and Fri. while quantitative confirmations are run Mon-Fri.

Results Reported

Typically, ≤ 4 business days from receipt for negative reports. For positive, quantitative reports ≤ 8 business days TAT from receipt.

Acceptable Matrices

Vitreous Fluid; 1 x 5 mL no-additive tube (red top). Any non-retrievable specimen will be considered.

Storage

Stored at 4oC until testing is completed. Long term storage of samples (1 year) is stored at -20oC.

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]).
