![]() The most popular device is the i-STAT (Abbot Point of Care, Princeton, New Jersey) over 30 studies have used the i-STAT system with elasmobranchs or teleosts, and it is commonly used for other taxa as well (Harter et al. However, researchers must exercise great caution because the devices were developed for human blood and, thus, often return incorrect values because of fundamental differences in fish and mammalian blood, including temperature, nucleated RBCs in fishes versus nonnucleated RBCs in humans, different pH effects on hemoglobin in teleost fishes (i.e., Root and Bohr shifts), and because the detection range is optimized for human blood parameters (see Harter et al. Originally developed for medical diagnostic purposes with humans, these so-called point-of-care devices are popular with fish biologists because they can be used in remote field settings with minimal training and can yield numerous blood parameters from a single blood sample (e.g., blood pH, hematocrit,, blood gases, HCO 3 −, ). In conclusion, the i-STAT system can easily generate fast resultsįrom rainbow trout whole blood, but many are inaccurate values. Is not recommended, due to significant effects of temperature, Hct and PCO2 on the measurement errors and complex interactions may exist. Application of conversion factors to correct i-STAT measurements SO2 did not yield meaningful results on rainbow trout blood. The algorithm that the i-STAT uses to calculate Measurements of Na+, PCO2, HCO3− and PO2 were variably inaccurate over the range of values typically found in fish. Haematocrit was consistently underestimated by the i-STAT, while the PH range and using the i-STAT temperature correction. Our results indicate that pH was measured accurately with the i-STAT system over a physiological This methodological comparison was performedĪt two temperatures (10 and 20☌), two haematocrits (low and high) and three PCO2 levels (0.5, 1.0 and 1.5%). (Hct), haemoglobin (Hb), HCO3−, partial pressure of CO2 (PCO2), partial pressure of O2 (PO2), Hb saturation (sO2) and Na+ concentration] in a model teleost fish (rainbow trout, Oncorhynchus mykiss) using the i-STAT system (CG8+ cartridges) and established laboratory techniques. The present study analysed a range of blood parameters [pH, haematocrit Poikilothermic fish, with only limited validation. Replace robust but lengthy techniques, researchers have extended the use of the i-STAT system outside of humans and even to Although originally conceived for clinical application and to Physiology because of their portability and easy operation. 50, dated July 26, 2011.Portable clinical analysers, such as the i-STAT system, are increasingly being used for blood analysis in animal ecology and Two 9-volt lithium batteries or rechargeable battery.įactory: electronic, mechanical, thermal, pressureġ5-40☌ (59-104☏) for Medisense strip testingġ6-30☌ (61-86☏) for i-STAT cartridge testingĬomplies with U.S.11 except for deviations pursuant to laser Notice No. Test results are uploaded automatically when the i-STAT 1 handheld is placed in a downloader.Operator lockout prevents unauthorized users from performing or viewing test results.Operator and patient information can be entered via barcode scanner.The system prompts users step by step through the testing process.Patient-side testing is as easy as entering the operator and patient information into the handheld, inserting one of the several testing cartridges, and then viewing test results: features ergonomically designed soft keys for comfort and ease of use.

In the USA, for the purpose of CLIA compliance, the i-STAT CHEM8+ cartridge is categorized as Waived. Analyzers, cartridges, and test strips should be used by healthcare professionals trained and certified to use the system and should be used according to the facility?s policies and procedures. The i-STAT 1 Analyzer is intended for use with i-STAT cartridges for in vitro quantification of various analytes in whole blood and with the Abbott MediSense Precision PCx Blood Glucose Test Strip for the in vitro quantification of glucose in whole blood. The Abbott i-STAT® 1 is a revolutionary handheld analyzer that provides labaccurate test results in minutes for a range of measurements including blood gases, electrolytes, chemistries, coagulation, haematology, glucose and cardiac markers.
