Advanced Diagnostic Laboratories

Lymphocyte Proliferation to PWM Mitogen

Test Code

WBMIT, LSTM

Description

Collect

Draw one green top tube (Sodium Heparin) top tube.

Specimen Preparation

Do NOT centrifuge! Keep at room temperature (18-22°C).

Preferred volume: 7 mL

Additionally, please send one normal control (sodium heparin green top tube) from a healthy, unrelated individual.

Patient Prep

POSITIVE PATIENT IDENTIFICATION [Labeling] requires we use two (2) pieces of information [identifiers].

The standard two patient identifiers for ADx Laboratories are patient FULL NAME and DATE OF BIRTH.
Limited exception for de-identified samples would be the sample NUMBER and patient DATE OF BIRTH.
Both identifiers must match exactly on the specimen label and the requisition/order that corresponds to that specimen.
Where appropriate for multiple samples submitted together, specimen collection information (e.g. site or source, date and time of collection, etc.) must also be included on the specimen label.

Pediatric Collection

Minimum volume: 2-3 mL blood

Unacceptable Conditions

Centrifuged specimens, specimens received after 24 hours of draw, frozen specimens, specimens in lithium heparin, specimens in tubes with gel such as SST's and PSTs.

Storage Transport Temp

Maintain and transport specimens at room temperature (18-22°C).
Ship specimens Priority Overnight via Fed Ex in container sufficiently insulated to avoid temperature extremes (<10°C and >37°C).

Stability

24 hours at room temperature (18-22°C)
