An Electronic Blood-Cell-Counting Machine

An electronic blood-cell counting machine.

A report on experience with an automatic blood counting machine.

Experience after 18 months' work with the SMA-4 system of multiple analysis for routine haematology is described, as well as the modifications to the machine which have been made for smoother operation.

Size distribution, electronic recognition, and counting of human blood monocytes.

During a study on the separation of human blood monocytes from lymphocytes, a method was developed to recognize and count monocytes by electronic means. Lightscattering (Cytograf, Bio/Physics), and changes in electrical resistance (Channelyzer, Coulter) were used to size mononuclear leukocytes directly in cell suspensions. Both methods revealed a size distribution profile in which two populatio...

Machine Learning Based Single-Frame Super-Resolution Processing for Lensless Blood Cell Counting

A lensless blood cell counting system integrating microfluidic channel and a complementary metal oxide semiconductor (CMOS) image sensor is a promising technique to miniaturize the conventional optical lens based imaging system for point-of-care testing (POCT). However, such a system has limited resolution, making it imperative to improve resolution from the system-level using super-resolution ...

A reliable screening protocol for thalassemia and hemoglobinopathies in pregnancy: an alternative approach to electronic blood cell counting.

Primary screening for thalassemia and hemoglobinopathies usually involves an accurate blood count using an expensive electronic blood cell counter A cheaper alternative method was tested by using a modified osmotic fragility (OF) test and a modified dichlorophenolindophenol (DCIP) test. Altogether 423 pregnant Thai women participated in this project. Hemoglobin patterns and globin genotypes wer...
