PMLSLEC NonBlood

Cards (223)

  • Nonblood specimens should be labeled with the same
    identifying information as blood specimens.
  • labeling should include the type and/or source of the specimen.
  • Because the lid is removed for testing, the label should be applied to the container, not the lid, so as to avoid misidentification.
  • It is important for the phlebotomist to verify proper labeling before accepting a specimen for transport.
  • The phlebotomist must be familiar with
    these requirements to protect the integrity of the
    specimen and help ensure accurate test results.
  • Nonblood body fluids are liquid or semiliquid
    substances produced by the body and found in the
    intracellular and interstitial spaces and within various
    organs and body spaces
  • most frequently analyzed nonblood body fluid.
    URINE
  • its analysis can provide information on many of the body’s major metabolic functions.
    URINE
  • If urine specimens are not tested promptly,
    urine components can change.
  • Inpatient urine specimen collection is typically handled
    by nursing personnel.
  • Outpatient urine specimen
    collection is often handled by phlebotomists.
  • In outpatient areas, written instructions
    are often posted on the wall in the restroom designated
    for patient urine collections.
  • The type of specimen preferred for many urine tests is the
    first urine voided (passed naturally from the bladder or
    urinated) in the morning, because it is the most
    concentrated.
  • A routine urinalysis (UA) is the most commonly
    requested urine test because it screens for urinary and
    systemic disorders.
  • A routine urinalysis (UA) is the most commonly
    requested urine test because it screens for urinary and
    systemic disorders.
  • involves macroscopic observation and notation of
    color, clarity, and odor, as well as measurements of
    volume and specific gravity (SG) or osmolality.
    Physical analysis
  • can detect bacteria, bilirubin, blood (red blood cells
    and hemoglobin), glucose, ketones, leukocytes,
    nitrite, protein, and urobilinogen, and measure pH
    and specific gravity.
    CHEMICAL ANALYSIS
  • Special timing, which is not the same for all tests, is
    involved in reading the results, which are reported in
    the manner indicated on the color chart.
  • trace, 1+, 2+,
    POSITIVE RESULT
  • negative (neg) or (-)

    NO REACTION IS NOTED
  • identifies urine components such as cells, crystals,
    and microorganisms by examining a sample of urine
    sediment under a microscope.
    MICROSCOPIC ANALYSIS
  • the ideal procedure for collecting a
    specimen for routine urinalysis is referred to as
    midstream collection.
  • Routine UA specimens should be collected in clear, dry,
    chemically clean containers with tight-fitting lids.
  • Specimens that require both UA and C&S testing should
    be refrigerated if immediate processing is not possible.
  • Specimens that cannot be transported or
    analyzed promptly can be held at room temperature and
    protected from light for up to 2 hours.
  • may be requested on a patient with symptoms of urinary tract
    infection (UTI).

    urine culture and sensitivity (C&S)
  • The culture involves placing a measured portion of urine
    on a special nutrient medium that encourages the growth
    of microorganisms, incubating it for 18 to 24 hours,
    checking it for growth, and identifying any
    microorganisms that grow.
  • Urine for C&S testing must be collected in a sterile
    container following midstream clean-catch procedures
  • are performed to detect
    cancer, cytomegalovirus, and other viral and
    inflammatory diseases of the bladder and other structures
    of the urinary system.
    CYTOLOGY STUDIES
  • Cells from the lining of the urinary tract are readily shed
    into the urine, and a smear containing them can easily be
    prepared from urinary sediment or filtrate.
  • RECOMMENDED CAPACITY OF URINE SPECIMENT
    50 ML
  • ML OF URINE SPECIMEN USES FOR MICROSCOPIC
    12 ML
  • SPECIMEN REJECTION:
    • improperly labeled and collected specimens
    • non matching labels and requisition forms
    • contaminated with feces/toilet paper
    • containers with contaminated exteriors
    • specimens of insufficient quality (QNS)
    • improperly transported specimens
  • Random refers only to the timing of the specimen
    and not the method of collection.
  • most commonly received specimen
    random urine
  • ideal screening specimen

    first morning/8-hour specimen
  • This type of specimen normally has a higher
    specific gravity, which means that it is more
    concentrated than a random specimen.

    first morning/8 hour specimen
  • safer, less traumatic method for obtaining urnie for bacterial culture and routine urinalysis
    midstream clean-catch
  • less contaminated by epithelial cells and bacteria
    midstream clean catch
  • is more representative of the actual urine than the routinely voided urine
    midstream clean-catch
