Retinol-binding protein stability in dried blood spots.
BACKGROUND Retinol-binding protein (RBP) is accepted as a surrogate biochemical marker for retinol to determine vitamin A (VA) status. A recently developed enzyme immunoassay for RBP uses serum or whole blood stored as dried blood spots (DBS). However, the stability of RBP in DBS has not been examined. METHODS RBP stability was studied in a laboratory and in field conditions in northern Kenya...

The multi-region hybridization assay (MHAbce) for genotyping HIV-1 subtypes B, C and circulating recombinant form (CRF01_AE) was evaluated on paired plasma and dried blood spots (DBS) collected from 68 HIV-1 infected individuals in Thailand. CRF01_AE was the predominant subtype identified using plasma samples (51/62) and DBS (24/27). There was no discordance in subtype designations between plas...
متن کاملDiagnosis of methylmalonic acidemia from dried blood spots by HPLC and intramolecular-excimer fluorescence derivatization.
Because of this specificity, a proportion of patients who are investigated for vitamin B 12 deficiency will end up being tested for the presence of IFABs, regardless of the diagnostic cascade favored by the investigating physician(s) (1, 2). In referral laboratories, this may lead to substantial test volumes of labor-intensive manual RIAs, with all the associated problems. These range from an i...
متن کاملAnalysis of 3,4-methylenedioxymetamphetamine: whole blood versus dried blood spots.
Analysis of dried blood spots is an increasingly accepted method in therapeutic drug monitoring, whereas its application by analogy to forensic samples has not been studied in detail. Therefore, we investigated whether determination of 3,4-methylenedioxymethamphetamine (MDMA) and its main metabolite 3,4-methylendioxyamphetamine (MDA) from dried blood spots (DBS) is as reliable as that from whol...
متن کاملMulti-mycotoxin analysis using dried blood spots and dried serum spots
In this study, a rapid multi-mycotoxin approach was developed for biomonitoring and quantification of 27 important mycotoxins and mycotoxin metabolites in human blood samples. HPLC-MS/MS detection was used for the analysis of dried serum spots (DSS) and dried blood spots (DBS). Detection of aflatoxins (AFB1, AFB2, AFG1, AFG2, AFM1), trichothecenes (deoxynivalenol, DON; DON-3-glucoronic acid, DO...
