[Prospects of the integration of dry blood spot technology with human health and environmental population studies].
This literature review is dedicated to prospects of the use of whole blood dried on special filter paper as a source of biological material for human health and environmental population studies. Evident advantages of this low-invasive approach include the following: it is easy to take a blood sample from a patient's finger ofa neonate's heel; the cost of sampling as well as transportation and storage of samples is low; paper blanks are safe to manipulate with and convenient to mail in sealed plastic packages. Many analytes, such as DNA, become more stable after drying, which allows for the detection of phenotypic and genotypic markers, as well as multiple gene mutations by multiplex DNA amplification. Modern diagnostic techniques make it possible to detect a wide spectrum of biomarkers characterizing the condition of the endocrine, cardiovascular, reproductive, and immune systems of the organism in a single drop of blood. This allows considering paper blanks with dry blood the key component of multilevel interdisciplinary population studies on neonatal screening, disease spread surveillance, seroepidemiological monitoring, and ecological and genetic research.
