Some analyzers offer a combined electrical and optical platelet count as standard. Depending on the size and complexity of the analyzer, a 3-part, 5-part or 7-part differential might be reported. The Coulter Principle2.
Hematology case studies for studentsSysmex has a small hematology analyzer designed specifically for the point-of-care environment, which offers 19 reportable parameters including a 3-part differential. There are four common causes of cellular interferences in the white cell chamber. Latest: Electrically conductive diluent is passed through a narrow channel.
Analyzers use a variety of technologies to determine this white cell differential. Some hematology analyzers for use at the point-of-care give only an Hb and HCT results. As this technology becomes more widely available, it will become increasingly accessible for hospital laboratories.
Hematology case studies for studentsOther point-of-care systems use dry hematology technology, which operate without bulky and costly reagent packs. Slide maker strainers are usually sold as part of a hematology solution. Vote Now for the Best New General Laboratory, Separations, and Spectroscopy Products of 2. However, analyzers without the ability to produce white cell scattergrams will not be as sensitive to these situations. I especially love that support staff can remotely diagnose and help resolve issues immediately. ”
, MD Anderson Cancer Center The CELL-DYN 3200 is very easy to use. Latest: Some manufacturers use a non-toxic method such as sodium lauryl sulphate solution instead of HiCN. Even small analyzers using this technology can give a white cell differential including granulocytes, lymphocytes and monocytes, as well as HCT, Hb, MCHC and platelet count. Latest generation analyzers are capable of giving detailed cellular information to the operator, such as blast cell differentials. Reticulocytes are counted by staining the RNA in the red cells using supravital, nucleic acid or fluorescent dyes. As each cell passes through an aperture, it causes a momentary drop in the electrical current being passed through the channel (the cells are nonconductive). Vacuum pump fluidic systems deliver perfectly precise volumes of diluents, samples and reagents to analysis chambers. Case report Research highlight Commentary Letter to Editor Studies The Department Pathology at University Pittsburgh School Medicine has formatted many pathology cases for online viewing rodak bf.

The most sophisticated analyzers are able to flag the possible causes of spurious red cell counts and parameters. Platelet counts determined using flow cytometry can help to resolve impedance platelet flags.

These include presence of cryoglobulins, cold agglutinins, and lipids. This can be useful for example on surgical and ITU wards. High-Performance Material Grinding Down into the Nano RangeLatest: Horiba also offers a small, compact analyzer which can be used in hospital settings such as the ED and ITU, or in the laboratory, and gives a 3-part differential as well as RBC and PLT parameters which include a PDW, PCT and RDW. The increased amount of data being provided to the operator as a result of these sophisticated technologies reduces manual review rates and improves laboratory efficiency. It is likely that we will increasingly see manufacturers partnering with digital imaging suppliers, and also developing this technology in-house. There are numerous analyzers on the market that can automate slide preparation and staining, and several instruments that are capable of actually reviewing the slides themselves. Fluorescence flow cytometry enables fluorescence platelet counts to be measured, as well as allowing the immature platelet fraction to be calculated, which can help clinicians to monitor thrombopoietic activity of the bone marrow. There are several situations that may lead to abnormal red cell counts; Red cells and platelets are usually counted together. When bone marrow regeneration begins, the IRF will increase after only a few hours, whereas the circulating reticulocyte count may take two or three days to show an increase. Fluorescent flow cytometry enables a reliable reticulocyte count at even extremely low concentrations, and in the presence of giant platelets.
This technology transformed the clinical laboratory into what it is today, and it would be very difficult to imagine how the modern hematology department would cope without it.
