blood and blood-forming tissues - ANSWER-The hematology department performs
laboratory tests that identifies diseases associated with what?
complete blood count (CBC). - ANSWER-What is the most commonly ordered
hematology test?
Coagulation - ANSWER-__________ is the study of the ability of blood to form and
dissolve clots.
blood-clotting mechanism. - ANSWER-Coagulation tests are closely related to
hematology tests and are used to discover, identify, and monitor defects in the
________________. They are also used to monitor patients who are taking medications
called anticoagulants (chemicals that inhibit blood clotting) or "blood thinners."
the prothrombin time, (used to monitor warfarin therapy), and the activated partial
thromboplastin time, (for evaluating heparin therapy) - ANSWER-What are the two most
common coagulation test?
chemistry - ANSWER-The ________department performs most laboratory tests. This
department often has subsections such as toxicology and radioimmunoassay.
serum - ANSWER-The most common chemistry specimen is ______; however, other
types of specimens tested include plasma, whole blood, urine, and various other body
fluids.
serology - ANSWER-The term ______ means the study of serum
Serology - ANSWER-_______ tests deal with the body's response
to the presence of bacterial, viral, fungal, or parasitic diseases stimulating antigen-
antibody
reactions that can easily be demonstrated in the laboratory
serologic - ANSWER-Autoimmune reactions, in which autoantibodies produced by B
lymphocytes attack normal cells, are becoming more prevalent and can be detected by
________ tests. Testing is done by enzyme immunoassay
(EIA), agglutination, complement fi xation, or precipitation to determine the antibody or
antigen present and to assess its concentration or titer.
, read - ANSWER-READ: The urinalysis (UA) department may be housed in the
hematology or chemistry area or may
be a completely separate section. Urine specimens may be analyzed manually or using
automated
instruments (Fig. 1-10). UA is a routine urine test that includes physical, chemical, and
microscopic evaluations (Table 1-14). The physical examination assesses the color,
clarity, and specificc gravity of the specimen. The chemical evaluation, performed using
chemical reagent strips, screens for substances such as sugar and protein and can be
read by hand,
visually, or with a urine analyzer. A microscopic examination establishes the presence
or
absence of blood cells, bacteria, crystals, and other substances.
microbiology - ANSWER-The ________department analyzes body fluids and tissues for
the presence of microorganisms, primarily by means of culture and sensitivity (C&S)
testing
particular antibiotics that would be most effective for treatment. - ANSWER-Results of a
C&S tell the physician the type of organisms present and the ___________. It is very
important to collect, transport, and handle microbiology
specimens properly in order to determine the presence of microorganisms and identify
them appropriately. An instrument used only for blood cultures makes it easy to identify
and
review the specimens for microbial growth, as shown in Figure 1-12. Subsections of
microbiology
are bacteriology (the study of bacteria), parasitology (the study of parasites), mycology
(the study of fungi), and virology (the study of viruses)
patient transfusions - ANSWER-The blood bank or immunohematology department of
the laboratory prepares blood products to be used for _______.
Histology - ANSWER-________ is defined as the study of the microscopic structure of
tissues.
histology cytology - ANSWER-Cytology and histology are often confused. Whereas
_______tests are concerned with the structure of tissue, ______ tests are concerned
with the structure of cells.
read - ANSWER-READ: An area found in larger labs is cytogenetics. In this section,
samples are examined for chromosomal
defi ciencies that relate to genetic disease. Specimens used for chromosomal studies
include tissue, blood, and amniotic fl uid. The DNA histogram is the latest such test for
genetic and malignant disorders. DNA fi ngerprinting and molecular genotyping have
become the prevalent form of scientific testing in forensic medicine.
