When collecting EDTA samples for TAC testing, it is important to ensure collection tube is drawn to its intended capacity. A partially filled tube increases the EDTA concentration and may cause an underestimation of the TAC result. Read EDTA study results

The prevalence of chronic kidney disease continues to rise globally. This educational white paper discusses the continuum of chronic kidney disease, and biomarkers available to help manage CKD patients.

This study illustrates assay performance in a population of 1000 Norwegian blood donors. Testing was performed to determine the serological profile that could be expected in such a population.

The CDC certification attests to the accuracy of the Siemens ADVIA Centaur® Vitamin D Total assay and its standardization to the RMP specified by the VDSP.

Siemens BNP assays demonstrate excellent precision and recovery from lot to lot. Room-temperature and refrigerated sample stability between the Dimension Vista and the TRIAGE BNP assays are similar.

The study described in this document demonstrates the alignment of the ADVIA Centaur® Vitamin D Total Assay to the 25(OH)vitamin D RMP and its impact on patient results.

What do Acridinium Ester and an INTEL computer chip have in common? Both AE technology and the Intel chip get better with age! Download this paper to read how!

This study demonstrates that the ADVIA Centaur® Vitamin D Total Assay traceable to the 25(OH)vitamin D RMP† was shown to be as accurate as LC/MS/MS in assessing vitamin D levels for patients on vitamin D supplementation.

Serology testing is important for identifying potentially chronic infections, which generally are asymptomatic until the late stage. In current treatment algorithms, molecular testing plays a key role in therapy and in assessment of therapy success.

Viral loads coupled with CD4+ T-cell counts help define therapy timing and assess treatment efficacy. Resistance testing guides the provider both in initial choice of therapy and in response to changes in drug resistance profiles.

Some genera of bacteria have emerged, particularly in the hospital setting, that are susceptible to very few antibiotics.Table 1 lists some of the more common bacteria that carry resistance to one or more antibiotics.

Testing for TORCH organisms can identify fetuses and neonates who are at significant risk. Serologic-based TORCH assays can identify infection and facilitate appropriate care thereby effectively reducing the risk of birth defects and fetal demise.

The aCCP assay on the IMMULITE® 2000 XPi has good performance characteristics and shows good concordance with the Immunoscan RA ELISA test, Immunocap 250 and aCCP test on the Roche Modular systems.

The study found that including TSI in hyperthyroidism testing algorithms would reduce net diagnostic costs by up to 43%, reduce net costs of misdiagnosis and treatment of unexplained symptoms by up to 85%, and reduce time to diagnosis by up to 46%.

The study demonstrates the impact of DBP concentration on the accuracy of the ADVIA Centaur® Vitamin D Total Assay at levels found in normal patient populations as well with clinical conditions such as pregnancy or chronic kidney disease was negligible.
