Body Fluid Counts and Differentials Quiz

A specialized type of control material used for validating the accuracy and precision of automated body fluid analysis systems.

Levels 1 and 2 refer to the different concentrations of analytes within the control material, allowing for assessment of both high and low ranges of measurement.

Storing controls outside the recommended temperature range can lead to degradation, affecting the reliability of test results.

When the control results consistently fall outside the expected ranges after troubleshooting, it suggests possible deterioration of the control material, requiring replacement.

A type of control material used specifically for manual cell count analysis of body fluids.

A major revision of a document or procedure, typically involving significant changes or updates.

A formal process of approving a document or procedure, ensuring it meets established standards.

A document version that has been replaced by a newer version.

The date the document was added to the system.

The date the document's content officially takes effect.

The date when the document's content officially stops being applicable.

A manual or automated process used to analyze body fluids, such as blood or urine.

An automated hematology analyzer used for counting and differentiating cells in body fluids.

A specialized type of blood test that analyzes the different types of cells present in a fluid sample.

The type of fluid being analyzed determines the specific cell types being counted. Different fluids have different normal cell populations.

A fluid differential involves counting 100 cells under a microscope to determine the percentage of each cell type present.

If a 100 cell differential is not possible, the count can be adjusted to a lower number or terminated using the 'Term' key.

Results considered abnormal, unusual, or suspicious require review by a pathologist.

The reference ranges for body fluid counts and differentials can be found in the Hematology Global Test Parameters.

Fluid counts are reported in the Laboratory Information System (LIS) using the 'MEM' function and a specific worksheet.

A type of counting chamber used for cell counting in laboratories.

A specific type of hemacytometer with a bright-line grid pattern.

The depth of the chamber where the cells are counted. Usually 0.1 mm.

The volume of the liquid contained over a specific area of the counting chamber. In this case, it's 0.1 microliter.

The pattern of lines on a hemacytometer, often using a specific grid like the Neubauer ruling.

A specific ruling pattern used in hemacytometers. It divides the grid into smaller squares.

The main grid lines of the Neubauer ruling, defining the boundaries of different areas.

The group of three lines on the Neubauer ruling, with the central line being the boundary.

When a fluid sample contains a high number of white blood cells (WBCs), a cytosmear slide is prepared to further examine the cells. This slide helps visualize the cells and allows for a more detailed analysis.

The procedure used to prepare a cytosmear slide involves spinning the fluid sample in a centrifuge called a 'cytocentrifuge'. This concentrates the cells onto the slide for clearer examination.

A special type of stain used to visualize white blood cells and their components on a cytosmear slide. It helps differentiate different types of white blood cells.

The amount of fluid used to prepare a cytosmear slide depends on its clarity. Clear fluids require a larger volume compared to cloudy or bloody fluids. This ensures optimal cell distribution on the slide.

A protein solution added to the fluid sample during cytosmear preparation. It helps minimize cell distortion and improve the yield of cells on the slide.

The speed at which the cytocentrifuge spins the fluid sample can be adjusted. If white blood cells are fragile, the spinning speed should be lowered to prevent damage.

The process of placing the prepared cytosmear slide in a special container or cytopsin. This ensures proper preservation and storage of the slide for further analysis.

Important information, such as patient name, sample identification number, date, and technician code, is written on the slide. This helps ensure proper tracking and identification of the sample throughout the analysis process.

A type of body fluid found in the space between the heart and the pericardium.

A type of body fluid found in the abdominal cavity.

A type of body fluid found in the space between the lungs and rib cage.

A type of body fluid obtained by washing the bronchi.

A type of body fluid collected from a Jackson Pratt drain.

A type of body fluid found in the amniotic sac surrounding the fetus.

A type of body fluid found in the spinal canal.

A type of body fluid collected from the peritoneal cavity.

A type of body fluid collected from the peritoneal dialysis system.

A type of body fluid found in the joints.

A fluid sample collected from a patient with a body fluid specimen.

An automated and manual procedure to count and differentiate cells in body fluids.

The color of the fluid sample.

Colorless
