Study Notes
Cerebral Spinal Fluid (CSF)
- CSF primarily functions to cushion and protect the brain and spinal cord, serving as a shock absorber.
- It helps maintain a stable environment for the central nervous system and facilitates nutrient delivery and waste removal.
Physical Appearance of CSF
- Normal CSF is clear, colorless, and free of significant turbidity or coloration, indicating healthy status.
Changes in CSF Appearance
- CSF can appear colored or cloudy due to infections, bleeding, or the presence of abnormal cells or proteins.
Lumbar Puncture
- A lumbar puncture, or spinal tap, is performed to collect CSF for diagnostic testing, relieving pressure, or administering medication.
Hemocytometer
- A hemocytometer is a specialized microscope slide used for counting blood cells in a given volume to assess cell concentration.
Early Hematology Analyzers
- The first hematology analyzers were based on manual counting methods, with some utilizing the principles of optical microscopy.
Complete Blood Count (CBC)
- A complete blood count (CBC) typically does not include parameters such as coagulation factors or specialized tests for certain blood disorders.
Purpose of a Hematology Analyzer
- The main purpose of a hematology analyzer is to automate the counting and classification of blood cells, improving efficiency and accuracy in laboratory diagnostics.
Counting Blood Cells in Early Labs
- Early laboratory technicians counted blood cells manually using microscopes and specialized counting methods, such as dilution techniques.
Evolution of Hematology Analyzers
- The evolution of hematology analyzers did not encompass manual techniques reliant solely on direct visual counting without electronic assistance or automation.
