Test ID: CHRGB    
Chimerism-Recipient Germline (Pre)

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Yes

Useful For Suggests clinical disorders or settings where the test may be helpful

Determining the relative amounts of donor and recipient cells in a specimen

 

An indicator of bone marrow transplant success

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

Initial Chimerism Testing

Complete chimerism analysis requires 3 specimens. These specimens should be submitted when collected. An interpretive report will be provided once all specimens are received.

 

CHRGB / Chimerism-Recipient Germline (Pre)

CHIDB / Chimerism-Donor

CHEP / Chimerism-Recipient Engraftment (Post)

 

Billing occurs with test codes CHRGB (for the Pre and Donor specimens) and CHMT / Chimerism-Recipient Engraftment (Post)

(Bill Only) (for the Post specimen). If an additional donor specimen is submitted, ADDO / Additional Donor will be performed at an additional charge.
