Fertility specialists use KIR genotyping, often paired with HLA-C typing, to assess maternal uterine natural killer cell receptor interactions during embryo implantation.
No. Because KIR genotyping is a DNA test performed on an EDTA venous blood sample, your result does not change with food, medication or menstrual cycle day.
KIR AA carries mainly inhibitory receptor genes, whereas AB and BB haplotypes include activating KIR genes. Your fertility consultant interprets the haplotype alongside HLA-C.
Yes. Sample collection £50 covers multiple blood tests taken in the same visit at 117a Harley Street.
