Specimen Required
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Specimen Type: Slide
Container/Tube: Plastic slide container
Specimen Volume: Smear
Collection Instructions:
1. Smears should be immediately fixed in 95% ethanol or sprayed with commercially available fixative. Smears that have been air-dried or Diff-Quik stained may also be accepted.
2. Label containers with a minimum of 2 unique identifiers (eg, patient name and medical record number or date of birth), specimen source, and date of collection. Label each glass slide in pencil with a minimum of 2 unique identifiers. If multiple slides are submitted, each slide must have proper identification.
Specimen Type: Fluid
Container/Tube: 60-mL (2 oz) jar with screw cap, 50-mL disposable centrifuge tube with screw cap, or 15-mL test tube with screw cap
Specimen Volume: Any amount
Collection Instructions:
1. Preferred method is no fixative added to fluid prior to processing and the specimen must be received and processed by the Cytology Laboratory within 1 hour of collection.
2. If not possible to submit within 1 hour, specimen should be refrigerated no longer than 62 hours. Additional acceptable fixatives are specimens with equal volume of 50%, 70%, 80%, or 95% ethanol, PreservCyt solution, CytoRich Red, or CytoLyt.
3. Label containers with a minimum of 2 unique identifiers (eg, patient name and medical record number or date of birth), specimen source, and date of collection.
Specimen Type: Tissue
Container/Tube: 50-mL disposable centrifuge tube with screw cap or 60-mL (2 oz) jar with screw cap containing 10% neutral-buffered formalin
Specimen Volume: Any amount
Collection Instructions:
1. Tissue fragments must be submitted in 10% neutral-buffered formalin.
2. Label containers with a minimum of 2 unique identifiers (eg, patient name and medical record number or date of birth), specimen source, and date of collection.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Aspiration cytology from a variety of organ sites is useful in the determination of pathologic states, particularly neoplasms. Commonly examined sites include lung, liver, lymph nodes, pancreas, kidney, thyroid, retroperitoneum, breast, salivary glands, and soft tissue. In many cases, an open biopsy is no longer required to make a diagnosis.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Negative for malignant cells
Interpretation
Provides information to assist in interpretation of the test results
Aspiration therapy is highly specific with rare false-positives. A positive diagnosis should be definitive for malignancy.
Precise cell typing is variably possible depending on circumstances.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Nondiagnostic results are issued when material is inadequate for a diagnostic impression.
A negative result must not be taken as definitive in the face of strong clinical suspicion. If the diagnosis is less than definitive (ie, suspicious), a follow-up biopsy may be recommended.
This test is not useful for most inflammatory conditions such as hepatitis, glomerulonephritis, etc. However, it may be helpful in obtaining material for culture and in identifying positive organisms in infectious diseases.
Slides must be fixed promptly after smearing to ensure adequate evaluation.

Method Description
Describes how the test is performed and provides a method-specific reference
Slides are stained by a modified Papanicolaou method and examined microscopically. DiffQuik stains may be used on air-dried specimens. On rare occasions, immunostains may be used secondarily as appropriate.(Unpublished Mayo method)
PDF Report
Indicates whether the report includes an additional document with charts, images or other enriched information
Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
Monday through Friday
Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
Specimen Retention Time
Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location
Indicates the location of the laboratory that performs the test
