Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
Assay & specimen
Class-level default (no specific cleared assay)— generic method inferred from analyte class; confirm against a specific product insert before use.
Specimen
Whole blood — gene is not a circulating analyte; measure protein product or genotype
Collection tube
K2-EDTA whole blood (lavender-top)
Method / principle
SNP genotyping / sequencing; or immunoassay of encoded protein
Reagent / substrate
Allele-specific primers/probes (TaqMan) or NGS panel; or antibody for protein
Platform
qPCR / NGS / array
Turnaround · availability
