| | NIEHS Press Release - EASIER WAY FOUND TO STUDY INTERACTIONS OF GENES, ENVIRONMENT |
 | | While sick people give blood almost as a matter of routine, the healthy controls may be scared of the needle, unwilling to be inconvenienced-or concerned about the privacy of the results. |
 | | While the blood from diseased patients is readily available for testing, in most cases, healthy volunteers often balk at the inconvenience of going to a clinic, or at the anticipated discomfort of the needle-or fear that, if a genetic susceptibility is found, it might become public, hurting their employability and insurability. |
 | | Even when blood samples may still be required for a study, the Umbach-Weinberg statistical proofs show that, if the exposure and the genetic susceptibility factor occur independently in the population, valid conclusions can be reached without linking the results, even by a number or code, to the volunteer who gave the blood sample. |
