Exam 30: Morphologic Analysis of Body Fluids in the Hematology Laboratory

The ability to bend light rays against both fixed and rotating filters is:

Accumulation of fluid as a result of systemic disease is defined as:

Which type of fluid is milky in appearance and is formed from long-standing effusions resulting from chronic conditions?

An effusion can accumulate as the result of a systemic disease and with congestive heart failure.The correct term for this fluid is:

List common morphologic changes associated with cytocentrifugation.

An unknown cell in a body fluid possesses the following morphologic characteristics: 35 mcM in size,partially clumped chromatin,prominent nucleoli,jagged nuclear membrane,and clumped cell with nuclear molding.What is the most likely identification of the unknown cell?

An unknown crystal exhibits positive birefringence.It is rhomboid in appearance.What is its most likely identification?

The following results are obtained from a 38-year-old woman with congestive heart failure: -Specimen: pleural fluid -Fluid protein = 4.5 g/dl -Serum protein = 9.5 g/dl -Serum LD = 110 U/L -Fluid LD = 60 U/L These results are most consistent with which of the following?

Malignant tissue cells have which of the following morphologic features?

A laboratician is scanning a cytospin and notices a few solid-staining wrinkled bodies on the cytospin prep.What is the most likely identification of this?

A peritoneal dialysate fluid is sent to the laboratory for analysis.Patient history reveals an 85-year-old woman with a previous history of duodenal cancer that is in remission.The laboratician reviews the cytospin and notices many large cells that are smooth in appearance and have abundant,basophilic cytoplasm with smooth nuclear membrane,evenly distributed chromatin,and no nucleoli.What is the most probable identification of those cells?

A 3-year-old boy is admitted with febrile seizures.A lumbar puncture is performed to rule out meningitis.The cytospin differential shows many large lymphoblasts with irregular nuclear membranes.This means that the patient:

A crystal with long,thin,needlelike,pointed ends is identified in synovial fluid.The crystals are located inside and outside the cells.A quartz compensator is used,and it determines that the crystals are negatively birefringent and are a yellow color when parallel to the axis of the compensator.The crystal is blue when turned perpendicular to the axis of the compensator.What is the type of crystal?

Cells found in fluids can be reactive mesothelial cells or malignant cells.Which features are found in reactive cells but not in malignant cells?

An overweight 73-year-old man sees his orthopedic specialist because of recurrent right knee pain.The physician performs an arthrocentesis and sends it to the laboratory for analysis.The technologist notes many crystals with notched edges,exhibiting strong birefringence.Based on this information,from what is the patient most likely suffering?

What fluid is collected from the subarachnoid space?

The technique that should be performed to differentiate starch particles from pathogenic crystals in fluids is:

Artifacts that can be seen with cytocentrifuge-prepared slides can be interpreted as a clinically significant finding by mistake.Which of the following can be an artifact leading to a mistaken interpretation of bacterial organisms in a fluid?

Explain how the following are formed: a.Transudate b.Exudate c.Chylous fluid

All of the following can be found in normal body fluid except:
