Write the date when you first open the pouch in the space provided on the label.
Recommended Assay Procedures
BD Trucount™ Tubes contain a known number of fluorescent beads, which is specified on the pouch label. This bead count is used by the flow cytometer software to calculate absolute counts of cells.BD Trucount™ Tubes are used with BD Multitest™ and BD Tritest™ reagents. See the instructions for use (IFU) for each reagent for the specific clinical applications.
BD Trucount™ Tubes can be used with the specimen types specified in the reagent IFU. See the appropriate reagent IFU for information about supported specimens, collection, storage, and preparation.
Reagents and materials provided.
BD Trucount™ Tubes come with two pouches of tubes. Each pouch contains 25 tubes, sufficient for 25 tests. Reagents and materials required but not provided.
• BD Multitest™ or BD Tritest™ reagent (see the reagent IFU for more information)
• BD FACS™ Lysing Solution (Catalog No. 349202)
The lysing solution is provided as a 10X concentrate and it contains diethylene glycol and formaldehyde. See the BD FACS™ Lysing Solution instructions for use (IFU) for precautions and warnings.

Reverse Pipetting
Accurate pipetting is critical when using a BD Trucount™ Tube. Use the reverse pipetting technique to add the sample to a BD Trucount™ Tube. For reverse pipetting, depress the button to the second stop. Release the button to draw excess sample into the tip. Press the button to the first stop to expel a precise volume of sample, leaving excess sample in the tip.
Staining the Cells
