Accessioning (Sir Gams PPT) Flashcards
Anatomic Pathology Laboratory Receiving
- Receiving (Request form, specimen)
- Logging
- Accessioning/ Numbering
T/F: Tissues removed from the body can be fixed within 1 hour of its removal.
FALSE, it should be fixed IMMEDIATELY!
The fixative should be __________ of the volume of the specimen
More than 10x
Process of giving an identifying marker to a
specimen
Accessioning/ Numbering
Accessioning starts in which area of the laboratory?
Receiving area
Specimens are logged based on the time it was?
Received
T/F: The middle name of the patient can be omitted from the request form.
FALSE, it should be included.
T/F: The date and time of request is the same as time of specimen removal.
FALSE, it is different.
Contents of clinical abstract
- Medical history of patient
- Chief complaint
- Details of the patient’s case
T/F: The tissue can be processed even if the information is not complete since it can be followed up.
FALSE, NEVER process samples with INCOMPLETE information
T/F: If the specimen number is S-2018-3IMT-2020, the specimen was received in the year 2020.
FALSE, it was received in the year 2018
Fixative for immunofluorescence
Saline or liquid nitrogen
This is used for renal and skin biopsies
Immunofluorescence
In immunofluorescence, __________ are utilized to detect a specific location in the tissue.
Antibodies
This provides rapid diagnosis
Rush Frozen Section
T/F: The fixative for the Rush Frozen section is formalin.
FALSE, there are no fixatives used in this section.
Specimens in the Rush Frozen section uses?
Liquefied CO2 or Liquid nitrogen
Clinical application of Rush Frozen section
Hirschsprung disease
This provides a high magnification to be able to see the ultramicroscopic details of a cell.
Electron Microscopy
T/F: Specimens are rejected IMMEDIATELY if the criteria is not met.
FALSE. Since specimens in histopathology are difficult to replace, troubleshoot first.
It is grounds for specimen rejection if the tissue has already gone?
Putrefaction
Ratio of tissue to formalin
1:10 or 1:20
Container for specimens
Leak-proof, must fit the specimen
Transport time should be _________________ of collection
Within 1 hour
Specimen Rejection criteria
- Condition of the specimen is not ideal for the test (unfixed/fixed)
- Quantity of fixative not sufficient
- Wrong container
- Long transport time
- Wrongly or incomplete filled request form
- Unlabelled/Mislabeled specimen
Receiving: Logging and Numbering
- Verify information on the request form
- Verification of the specimen label
- Enter all data in the logbook/LIS
- Accession/Number the specimen
Importance of Accessioning
- Avoid mixing/switching of specimen
- Track down specimen/results
- Prevents mismanagement of specimen
- Process the right specimen
- Accurate and Timely results
- Proper Management/treatment at the right time
- Record keeping
- Laboratory Planning
This is the first step in Histopathologic techniques
