Subcutaneous Fat Aspirate
Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
The following information is required:
1. Patient's date of birth
2. Name and telephone number of ordering physician
3. Pertinent clinical information
Container/Tube: Glass slides or sterile container
Specimen Volume: Minimum of 4 slides or 1 cubic mm
1. Sterilize and anesthetize a small area of the anterior abdominal wall.
2. Aspirate subcutaneous fat through a large bore needle.
3. Apply the fat obtained in the syringe directly to a glass slide and crush with a second slide.
4. Air-dry the slides and send without fixative.
5. Alternately, send fat in small container of saline.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
