Mitogen-induced Lymphocyte Proliferation Panel (PHA, Con A, PWM)

Test Summary

Measurement of human lymphocytes' proliferative responses to various stimuli is a fundamental technique used to assess their biological status and functions. Mitogens, such as plant lectins phytohemagglutinin (PHA), concanavalin A (Con A) and pokeweed mitogen (PWM), are able to nonspecifically stimulate lymphocyte proliferation and used to evaluate patient immune responsiveness.

Specimen Collection

Special Instructions

N/A

Preferred Specimen

10 mL whole blood collected in a sodium heparin (green-top) tube

Minimum Volume

5 mL

Instructions

Whole blood must be transported at room temperature and delivered to the testing laboratory within 48 hours after collection.
Maintain and transport blood at room temperature. Avoid temperatures <15° C and >37° C. In hot weather, it may be necessary to pack the specimen in a container with insulating material around it and place this container inside another one that contains a cold pack (ice pack) and absorbent material. This method will help retain the specimen at ambient temperature. For longitudinal studies, draw specimens at the same time of day to minimize diurnal variation.

Clients: Contact the lab prior to ordering for special logistics arrangements.
PSC: Follow Short Stability Protocol.

Test available by prior arrangement only. Special sample collection and transportation arrangements must be made prior to ordering the test. Contact your local Customer Service Department and request to speak to someone in Referral Testing Department for specific instructions.
Submit Monday-Thursday only. Do not draw day before a holiday. Samples received in testing lab >48 hours after collection will be rejected. Date and time of draw are required and must be provided.
