Exam 30: Morphologic Analysis of Body Fluids in the Hematology

List common morphologic changes associated with cytocentrifugation.

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?

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

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?

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

Morphologic evaluation of body fluids prepared by using the cytocentrifuge is an excellent method of concentrating cells for microscopic review. When the pleural fluid is cytocentrifuged for staining, what type of normal cells would one expect to see?

One of the definitive signs of hemorrhage in the CNS is:

An exudative effusion can cause many different pathologic processes, such as bacterial infections, viral infections, neoplasms, and collagen vascular diseases. What are the typical laboratory results of an exudate?

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

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 is the significance of micro-organisms present in the cytospin?

What type of fluid is collected from the spinal tap or lumbar puncture procedure?

A laboratician is scanning a cytospin slide from a CSF specimen and notices a few solid-staining wrinkled bodies on the cytospin prep. A follow up India ink prep is positive. What is the most likely identification of this?

Lamellar bodies can be counted on a hematology analyzer because they are similar in size to what cell type?

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

A specimen labeled "ascites" is sent to the laboratory. What type of procedure was used to obtain this fluid?

List the basic battery of tests for a routine semen analysis and cite the reference range for each.

A technologist is performing a body fluid analysis on a CSF specimen recently received in the laboratory. Four CSF tubes were sent to the body fluids bench. The tech notices that all four specimens seem moderately blood tinged equally. Moderate xanthochromia was also noted. The tech performs the cytospin differential and notices many macrophages with black crystals and round, pink intracellular bodies. What is the most likely reason for these findings?

Examination of joint fluid on a 60-year-old patient with right knee pain reveals many intracellular needlelike crystals that polarize yellow to blue. What is the most likely identification of the crystal?

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