A simple method to quantitate IP-10 in dried blood and plasma spots. [PDF]

PLoS ONE, 2012
BACKGROUND: Antigen specific release of IP-10 is an established marker for infection with M.tuberculosis. Compared to IFN-γ, IP-10 is released in 100-fold higher concentrations enabling the development of novel assays for detection. Dried blood spots are

Evaluation of Dried Plasma Spot-Based Quantification of Glial Fibrillary Acidic Protein as a Disease-Associated Biomarker in Neuromyelitis Optica Spectrum Disorder. [PDF]

Ann Clin Transl Neurol
ABSTRACT Objective To evaluate the diagnostic accuracy of glial fibrillary acidic protein (GFAP) measured in dried plasma spots versus conventional plasma‐ and serum‐GFAP testing for assessment of disease severity in aquaporin‐4 immunoglobulin G–positive neuromyelitis optica spectrum disorder (AQP4‐IgG+ NMOSD).

Exercise, Training & Health

Deutsche Zeitschrift für Sportmedizin, 2022
Rationale: Anti-SARS-CoV-2 antibody responses elicited by infection or vaccination vary among individuals and over time. Their knowledge is of particular importance in, amongst others, elite sport. Can dried blood spots serve as a minimally-invasive, low-

The development and validation of dried blood spots for external quality assurance of syphilis serology. [PDF]

, 2013
BACKGROUND: Syphilis causes up to 1,500,000 congenital syphilis cases annually. These could be prevented if all pregnant women were screened, and those with syphilis treated with a single dose of penicillin before 28 weeks gestation.

Comparison of cross-sectional HIV incidence assay results from dried blood spots and plasma. [PDF]

PLoS ONE, 2017
BACKGROUND:Assays have been developed for cross-sectional HIV incidence estimation using plasma samples. Large scale surveillance programs are planned using dried blood spot (DBS) specimens for incidence assessment. However, limited information exists on

Detection of HIV-1 infection in dried blood spots from a 12-year-old ABO bedside test card [PDF]

, 1998
Background and Objectives: We tested dried blood from an ABO bedside test card which had been stored at room temperature for 12 years, to prove that a patient with HIV-1 infection had been infected by blood transfusion. Materials and Methods: Immunoblots

Pharmacokinetic study of praziquantel enantiomers and its main metabolite R-trans-4-OH-PZQ in plasma, blood and dried blood spots in Opisthorchis viverrini-infected patients [PDF]

, 2016
Praziquantel (PZQ) is the treatment of choice for infections with the liver fluke Opisthorchis viverrini, a major health problem in Southeast Asia. However, pharmacokinetic (PK) studies investigating the disposition of PZQ enantiomers (R- and S-PZQ) and ...

A New Fluorescent Method to Detect Sulfamidase Activity in Blood, Tissue Extracts and Dried Blood Spots

Journal of Inborn Errors of Metabolism and Screening, 2021
Mucopolysaccharidosis type IIIA (MPS IIIA) is a lysosomal storage disorder due to the deficient activity of sulfamidase (SGSH). Traditionally, measurement of this enzymatic activity has been performed using a fluorescently (4-MU) labeled glycoside ...

Filter paper blood spot enzyme linked immunoassay for adiponectin and application in the evaluation of determinants of child insulin sensitivity. [PDF]

PLoS ONE, 2013
Adiponectin is an adipocyte-derived hormone that acts as a marker of insulin sensitivity. Bloodspot sampling by fingerstick onto filter paper may increase the feasibility of large-scale studies of the determinants of insulin sensitivity.
