CD57 Antibody Monitoring
Test Code: CD57
Synonyms/Keywords
Flow Cytometry​, CD 57
Useful For
Changes in the CD57 subset may be useful to monitor the response to therapy in Lyme disease.​
Specimen Requirements
Fasting Required Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)		 Pediatric Minimum Volume
(no repeat)
No​ Whole Blood​ Sodium-heparin Green Top Tube (GTT)​ ​** EDTA 1.0 mL​ 1.0 mL​ 0.5 mL​
Collection Processing Instructions

If a CBC with differential has been performed within 4 hours of the collection for the CD57, please send a copy of the CBC with differential results along with the CD57 specimen. If a CBC with differential has not been performed in this time period, include an order for the CBC with differential. This requires a separate EDTA whole blood (LTT) and two unstained EDTA smears. Notify Flow Cytometry Lab (800-222-5835, ext. 16385) before sending the specimen.

Specimen must arrive in Flow Cytometry within 48 hours of collection. ​
