Routine use of hair root or buccal swab specimens for PCR analysis: advantages over using blood.
We report the use of hair roots and buccal cells as specimens of choice for DNA analysis of genetic diseases in a service laboratory. Our protocols using these specimen types show superiority to those using blood specimens in the areas of collection, transport, storage and overall cost. Our experience using these specimen types for 319 cystic fibrosis delta F508 mutation tests and 62 Leber's hereditary optic neuroretinopathy mutation tests leads us to recommend that hair roots and buccal cells should be evaluated as specimens of first choice when developing PCR DNA analysis.
