Flow Cytometry

Flow Cytometry

The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Glassware Calibration

Glassware Calibration

Accurate calibration of glassware, such as volumetric flasks, pipettes, and burettes, is essential to ensure accurate measurements in the analytical laboratory. Calibration helps maintain consistency across measurements and prevents errors arising from inaccurate volumes.
Volumetric flasks: Volumetric flasks are designed to prepare aqueous solutions of precise volumes accurately with a calibration line on the neck. To calibrate a volumetric flask, it is important to fill it with distilled...

Area of Science:

Clinical diagnostics
Hematology
Flow cytometry

Background:

Accurate absolute leukocyte enumeration is essential in clinical practice.
Current methods for determining leukocyte counts often involve adding reference beads to blood samples.
The necessity of adding beads solely for pipetting error assessment is debated.

Purpose of the Study:

To present technical details for flow rate calibration in leukocyte enumeration.
To introduce a method that obviates the need for reference beads in each sample.
To lay the groundwork for clinical evaluations of a novel approach to absolute leukocyte counts.

Main Methods:

Development of a flow rate calibration technique.
Technical description of the calibration procedure.
Focus on eliminating the need for internal quality control beads per sample.

Main Results:

A method for flow rate calibration has been established.
The proposed calibration obviates the need for reference beads in individual samples.
Technical details are provided for implementation.

Conclusions:

The developed flow rate calibration offers a novel approach to absolute leukocyte enumeration.
This method may streamline the process by removing the requirement for sample-specific reference beads.
Further clinical evaluations are anticipated to validate this technique.
