![]() This problem notwithstanding, the successful implementation of the PCA is attributed to careful analytical evaluations and ongoing communication with the clinical staff. After the PCA was implemented for clinical testing, the observation of discrepant results of creatinine concentrations in neonatal blood samples that would have affected clinical management led to a second creatinine comparison study (59 additional samples) and to our eventual discontinuation of the PCA creatinine assay. Reproducibility (CV) was good ( or < 3 mo) showed that agreement between the PCA and the primary methods was clinically acceptable. Four cartridge types: (a) EC8+ (sodium potassium chloride urea glucose pH blood gases ), (b) EC6+ (sodium potassium ionized calcium glucose hematocrit pH), (c) G3+ (pH PO2 pCO2), and (d) creatinine, were assessed for reproducibility, linearity, and method comparisons using aqueous samples, blood samples supplemented with several analytes, and -225 blood samples from patients. Our objective was to determine whether PCA measurements at the bedside of patients in the neonatal and pediatric intensive care units of the MUSC Children's Hospital would be as reliable as those performed by the clinical laboratory's primary methods (Radiometer ABL 725 blood gas analyzer Vitros 750 chemistry analyzer and Coulter STKS hematology analyzer). ![]() This includes medicines that don't need a prescription and any illicit drugs you may use.We evaluated the analytical performance of the i-STAT Portable Clinical Analyzer (PCA), a point-of-care testing system consisting of a hand-held analyzer and single-use cartridges that measure different panels of electrolytes, metabolites, blood gases, and hematocrit in 65-100 microl of blood. Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. Being pregnant or being older than 60 can cause your HCT to be lower than normal.Ĭertain medicines can also affect your results. Living at a high altitude may cause your HCT to be higher than normal. When the needle pricks your arm or hand, you may feel a slight sting or pain. These include bleeding, infection, bruising, and feeling lightheaded. Having a blood test with a needle carries some risks. A needle is used to draw blood from a vein in your arm or hand. White blood cell cancers, such as leukemia If your HCT is low, it means you may have: ![]() This can happen when you are dehydrated or in shock. Your HCT may also be high if your plasma or blood volume is too low. If your HCT is high, it may mean your body is making too many red blood cells. Normal values are:ģ0% to 44% for children, depending on age POC devices (the Radical-7, i-STAT, and GEM 4000) and a reference laboratory device (UniCel DxH. Normal hematocrit values are different for men, women, and children. Interventions: Hgb and Hct values were measured using 3. Ask your healthcare provider what your test results mean for you. Your test results may not mean you have a problem. Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your healthcare provider may also order a test that measures your hemoglobin to find out how much oxygen your red blood cells are carrying. Your healthcare provider may also order a complete blood count, or CBC, which is a blood test that counts all the different types of cells in your blood. What other tests might I have along with this test? Too few red blood cells is called anemia.Īnemia can be caused by blood loss, your body making fewer red blood cells, or increased destruction of red blood cells. Too many red blood cells is called polycythemia. You may also need your hematocrit checked before having surgery or if your healthcare provider suspects you have a red blood cell disorder. You may need this test if it is part of routine blood testing. To measure your HCT, your blood sample is spun at a high speed to separate the red blood cells. Your hematocrit (HCT) shows whether you have a normal amount of red blood cells, too many, or too few. In this test, your red blood cells are separated from the rest of your blood so they can be measured. Normal blood contains white blood cells, red blood cells, platelets, and the fluid portion called plasma. All analyses were performed by certified. ![]() 0001) in the hematocrit range below 25 (n 11) using the i-STAT. This test measures how much of your blood is made up of red blood cells. The same sample was used to fill the cartridge for the i-STAT and two centrifuge tubes for the spun hematocrit. In contrast to hematocrit measured during CPB, hematocrit using the non-CPB mode in the non-cardiac intensive care population showed an underestimation up to 2.2 (p <. HCT, packed cell volume, PCV What is this test? Hematocrit Does this test have other names? ![]()
