The investigators said the infants participating in the pilot program won't undergo any additional blood sampling since the new screening test is designed to utilize the
standard dried blood spot samples already collected from all babies born in the United States.
In the present study, led by Professor Ulf Landegren at Uppsala University / SciLifeLab, the researchers
analysed dried blood spots.
Other studies included use of rapid tests for HIV, HBV and HCV for emergency field testing of the «Walking Blood Bank» in military operations; use of
dried blood spots for collection of specimens in the field for testing of HIV, Dengue, West Nile Virus and Chikungunya Virus; and molecular assays for monitoring Chlamydia trachomatis, Neisseria gonorrhoeae, Ebola virus, and other infectious agents in epidemiology and vaccine research studies.
Her research utilises the immuno - SRM platform to detect tryptic peptides
in dried blood spots and predict immunogenicity to enzyme therapy in patients with infantile Pompe disease and other lysosomal storage diseases.
Plans for an expansive collection of biological samples, including cheek swabs for DNA,
dried blood spots to test immune function, and saliva for additional cortisol levels, had to be pared back.
First, you can prick your own finger and send in
a dried blood spot by post.
«Our conclusion is that we can measure levels of 92 proteins with very high precision and sensitivity using PEA (Proximity Extension Assay) technology in the tiny, punched - out discs from
a dried blood spot.
The test is done by
dried blood spot from a finger prick.
