At HyTest, scientific research is a cornerstone of our product development. An integral part of research is made up of the articles that are published in peer reviewed journals. This year, three different studies conducted by our R&D team have already been published– specifically, two research articles and one review.
1) Review of BNP and NT-proBNP standardization – receive a free copy!
“Standardization of BNP and NT-proBNP immunoassays in light of the diverse and complex nature of circulating BNP-related peptides” has been published as a chapter in Advances In Clinical Chemistry.
Both BNP and NT-proBNP are established markers of heart failure that are used in clinical practice for several purposes: to identify or exclude heart failure, to assess the severity of the disease, for risk stratification, as well as to monitor the response to therapy. In order to measure BNP or NT-proBNP, there are several diagnostic assays available that are widely used in clinical practices. Unfortunately, the results of measurements that are obtained with different assays are not sufficiently comparable and this can easily cause problems in daily practice.
The aim of this review is to “summarize the available data on the complex nature of BNP-related peptides, specificity for existing BNP and NT-proBNP immunoassays and to discuss potential approaches for the standardization of BNP and NT-proBNP measurements.”

2) Research article about glycosylated and non-glycosylated NT-IGFBP-4. Open access.
Along with novel data regarding the regulation of bioavailability of IGF hormone by IGFBP-4 glycosylation, this article describes HyTest’s prototype HRP-based immunoassay for NT-IGFBP-4. The assay is validated according to the requirements of clinical journals and it is utilized for NT-IGFBP-4 measurements in the samples from acute coronary syndrome patients.
