Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
89740
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Conditional
Useful For Suggests clinical disorders or settings where the test may be helpful
Preferred test for confirming a diagnosis of X-linked agammaglobulinemia (XLA) in male family members of affected individuals with known BTK mutations
Preferred test for determining carrier status of female relatives of male XLA patients with known BTK mutations
By including both protein and gene analysis, this test provides a comprehensive assessment and enables appropriate genotype-phenotype correlations
Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| BTKKM | BTK Gene, Known Mutation | Yes, (order BTKK) | Yes |
| BTKKQ | BTK Gene, Known Mutation Sequencing | No | Yes |
| BTK | Btk Protein Flow, B | Yes | Yes |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
When this test is ordered, a DNA extraction will always be performed at an additional charge.
Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
