Test Catalog

Test ID: HMDP    
Hyperimmunoglobulin M (Hyper-IgM) Defects Panel

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

Diagnosis of hyper-IgM syndromes, specifically X-linked hyper-IgM (HIGM1) and autosomal recessive hyper-IgM type 3 (HIGM3)


Evaluation of isotype class-switching defects

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 IDReporting NameAvailable SeparatelyAlways Performed
TBBST- and B-Cell QN by Flow CytometryYesYes
IABCImmune Assessment B Cell Subsets, BNoYes
CD40CD40 by Flow, QL, BYesYes
XHIMX-Linked Hyper IgM Syndrome, BYesYes

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

When multiple specimen types are required to perform a panel of tests, the laboratory will perform the tests for which the appropriate specimen type was received and the laboratory will cancel those for which the appropriate specimen was not received. Please be advised that this may change the degree of interpretation received with the report.
