مایع رقیق کننده CSF

CSF Diluting Fluid is a specialized solution used in microbiology and clinical laboratories to dilute cerebrospinal fluid (CSF) samples before performing a cell count, especially in cases of suspected infection or inflammation. It is commonly used during routine diagnostic procedures, such as the analysis of white blood cell counts in CSF.

🏭⚗️ Production
CSF Diluting Fluid is typically prepared by dissolving specific salts, such as sodium chloride (NaCl), in water to create an isotonic solution. Sometimes, additional chemicals like formalin or acetic acid are added to fix the cells and prevent them from deteriorating during the counting process. The formulation of the fluid is designed to maintain the osmotic balance of the CSF sample, ensuring that cells do not swell or shrink during analysis.

🔬 Properties
The CSF Diluting Fluid is usually a clear, colorless solution that has an isotonic or slightly hypertonic composition. This helps to maintain the integrity of the cells present in the CSF, particularly white blood cells and red blood cells, during dilution. In some formulations, formalin or other preservatives are included to stabilize the cells for easier counting under a microscope. The fluid is designed to not interfere with the cellular morphology of the CSF sample.

🧪 Applications
Cell Count in CSF: CSF Diluting Fluid is primarily used to dilute cerebrospinal fluid samples during the process of cell counting, particularly to estimate the number of white blood cells (WBCs) and red blood cells (RBCs) present in the CSF. Elevated white blood cell counts in CSF can indicate infection or inflammation in the central nervous system (CNS).
Microbial Examination: The fluid is also useful in the microbiological analysis of CSF, where cell counts are correlated with the presence of microorganisms like bacteria, fungi, or viruses, aiding in the diagnosis of meningitis, encephalitis, and other CNS infections.
Routine CSF Analysis: In laboratories, CSF Diluting Fluid is used during routine diagnostic procedures to prepare the sample for further tests like bacterial cultures or PCR assays.
