Detection of antibodies against hepatitis A in blood spots dried on filter paper. Is this a reliable method for epidemiological studies?

Hepatitis B virus markers on dried blood spots. A new tool for epidemiological research.

a simple rapid procedure for hemoglobin electrophoresis using a drop of dried blood on filter paper

a simple, rapid new technique is described for the electrophoresis of hemo­globin when screening large human populations. the method uses a drop of finger tip's blood dried on a thick filter paper as the specimen. the simplicity of the sampling, tagging, transportation and electrophoresis, provides a reliable procedure for surveys of large population. in our hand 200 specimens were screened dur...

Micromethod for estimating adenosine deaminase activity in dried blood spots on filter paper.

We describe a fluorometric micromethod for measuring adenosine deaminase activity in dried blood spots on filter paper. Earlier methods require venipuncture and preparation of washed erythrocytes; in the present method, whole capillary blood, spotted on filter paper and mailed (dried) to a central laboratory, is used. The stability of the enzyme in dried blood on filter paper was assessed. The ...

Utility of PCR for DNA analysis from dried blood spots on filter paper blotters.

T h e collection of dried blood spots on filter paper blotters is a major innovation and has facilitated the development and dissemination of newborn screening programs principally because of the ease of sample collection, handling, and shipment to centrally located laboratories and the stability of the analytes in these specimens. (1,2) These samples, which are also known as "Guthrie spots," a...

Analysis of the Stability of Urea in Dried Blood Spots Collected and Stored on Filter Paper

The ability to use dry blood spots (DBSs) on filter paper for the analysis of urea levels could be an important diagnostic tool for areas that have limited access to laboratory facilities. We developed a method for the extraction and quantification of urea from DBSs that were stored on 3M Whatman filter paper and investigated the effect of long-term storage on the level of urea in DBSs. DBSs of...
