LAB MANAGEMENT :: ANALYZERS Rollins points to the Nova Prime Plus
blood gas/critical care analyzer, which has been specifically developed for point-of- care testing of high acuity ICU and hos- pital ward patients. Prime Plus provides the most comprehensive menu of critical care tests from a single 135 µL whole blood sample in about one minute at the point of care. Its menu of 22 diagnostic tests helps clinicians manage a broad spectrum of vital physiological functions, including respiratory function and blood gases; acid/ base balance; electrolyte balance including ionized magnesium (one of the most im- portant yet often unmeasured electrolytes); kidney function; fluid balance; anemia; tissue perfusion; and glycemic control.
LumiraDx SARS-CoV-2 Antigen test is a rapid antigen test, but more specifically it is a Rapid Microfluidic Immunofluo- rescence assay. “What sets our test apart from tradi-
tional lateral flow tests is our next genera- tion microfluidic technology,” said Noel.
Individual lab needs Martin Conway, Marketing Manager, Randox Laboratories, reminds laboratory professionals that the choice of analyzer ultimately comes down to each lab’s specific needs, stating:
“Laboratories across the globe all differ in testing capabilities, size and experi- ence. There are many different factors that laboratory users should consider such as the throughput of the instrument – does it meet their testing requirements, size of the instrument, ease of use, analyzer downtime/uptime, testing menu, sample types, sample volume, STAT capabilities, QC capabilities, ISE testing and time and cost to the laboratory.”
“Laboratory automation and analyzer
versatility has driven the demand for larger throughput instruments in the

Rollins notes how the Nova Prime Plus blood gas/critical care analyzer connects the test results to the patient record and makes them available for clinician review at the patient bedside. He states: “They are easily connected to the electronic medical record and other data sites with Nova’s extensive NovaNet middleware, which is already in use by more than two thirds of U.S. hospitals to connect Nova StatStrip bedside glucose measurements.”
Quality control According to Noel, clinical labs are dis- covering the utility of next generation point-of-need tests when it comes to quality control (QC), stating: “Although software features like QC lockouts, operator certification expiration, and expired test strip lock- outs were designed to support quality management outside the clinical lab, in conversation with lab directors some have indicated these are great fea- tures no matter the setting. The level of stringency may differ but the features themselves are impactful.”

“In contrast to the passive action of lateral flow methods, our microfluidic technol- ogy allows us to control every aspect of the test process including mixing, tem- perature, timing, incubation, magnetic capture, and signal detection. This next generation technology is how we attain near PCR sensitivity superior to lateral flow methods. Although this is designed to bring lab-comparable testing closer to the point-of-need, several large academic in- stitutions are running this in their clinical lab due to the features discussed above.”
Supply chain factors Supply chain disruptions ushered in by the COVID-19 pandemic continue to impact clinical lab operations. Among lab professionals surveyed in 2022, 58% said they have utilized multiple testing plat- forms as a best practice to address supply- chain issues during the pandemic.1 “In addition to metrics such as
throughput and footprint, clinical labs should also consider supply chain risks inherent in the global marketplace when evaluating a new analyzer,” said Shugart. “For example, the CLC Family of Instru- ments from Carolina Liquid Chemistries offers options for testing chloride, po- tassium and sodium using either an Ion Selective Electrode (ISE) method or switching to a moderate complex- ity photometric method in the event of supply disruption. The CLC Family, com- prising the very high-volume CLC6410, high-volume CLC1600, and mid-volume CLC800, are fully automated and have extensive test menus.”

market such as the Randox RX Modena,” Conway added. “However, for some laboratories, smaller benchtop platforms and semi-automated instruments meet particular needs, most importantly, the time and cost savings over dry and wet chemistry laboratory testing, like that of protein specific testing where laborato- ries can install an RX instrument over a nephelometer.” Conway says Randox chemistry instru- ments are designed to offer laboratories a world leading test menu comprising over 100 dedicated high-performance assays with excellent CVs, consolidation of routine and novel tests with maximum uptime via robust hardware, minimal maintenance, unparalleled supports to improve operator costs, automation, data management, and sample handling.
