|September 1, 1986
Summary
This study introduces a membrane filter technique for cerebrospinal fluid (CSF) cytology, improving cell retrieval and evaluation time. The method efficiently analyzes CSF specimens, aiding in the diagnosis of various conditions.
Area of Science:
- Cytopathology
- Neurology
- Medical Diagnostics
Background:
- Cerebrospinal fluid (CSF) analysis is crucial for diagnosing neurological conditions.
- Traditional CSF cytology methods can be time-consuming and may have limitations in cell retrieval.
Purpose of the Study:
- To evaluate a semiquantitative membrane filter approach for cerebrospinal fluid (CSF) cytology.
- To assess the efficacy and advantages of this new technique in routine laboratory settings.
Main Methods:
- A total of 535 CSF specimens were processed using a 25-mm diameter Millipore filter (5-µm pore size).
- Specimens were stained with a modified Papanicolaou method for microscopic evaluation.
- Evaluations included cell count per milliliter, a 100-cell differential, and a diagnostic statement.
Main Results:
- The study evaluated 74% positive, 17% atypical, 439% negative, and 4% unsatisfactory specimens.
- Seventy-four percent of positive or atypical CSF specimens showed mononuclear cell counts within the normal range.
- The membrane filter technique maximized cell retrieval, localized cells, and reduced evaluation time.
Conclusions:
- The semiquantitative membrane filter approach is an effective method for CSF cytology.
- This technique offers significant advantages in cell retrieval, localization, and efficiency for microscopic evaluation.
- It provides a valuable tool for the cytological examination of cerebrospinal fluid.
