Biochip array technology for new psychoactive substances detection in biological samples: Evaluation of the specificity of the Randox Evidence Investigator.

Background: The need to detect new psychoactive substances in biological samples is of crucial interest. In this paper, the specificity of a benchtop immunoanalyzer commercialized by Randox was evaluated on real patient samples.

Method: The Evidence Investigator was assessed to screen for NPS on 80 serum and urine samples coming from patients admitted to the emergency department.

Laboratory evaluation of the new Access ® cytomegalovirus immunoglobulin IgM and IgG assays.

Background: Reliable laboratory methods for detecting congenital CMV infection are valuable since CMV infections are asymptomatic and because early detection is important for correct management and counseling of expectant mothers.

Objectives: Compare the Beckman Coulter Access(®) method for the Unicel(®) DxI 800 analyzer with the bioMérieux VIDAS(®) method for two serological markers: CMV IgG and CMV IgM.

Study Design: Precision was determined with CLSI EP5-A2 protocol.
