Bio-Material
To obtain DNA, a blood or saliva sample was collected, DNA was extracted
and stored in the LATER study biobank. Additional blood samples were
drawn from survivors and siblings and stored in -80°C in several
aliquots for study questions and future central analyses. For specific
outcomes (renal and splenic function), blood was analyzed directly in
the lab of the local center. For some sub-studies, we also collected a
semen specimen, urine sample, and saliva sample.
