||
Geisinger Epic Procedure Code: LAB4794
Geisinger Epic ID: 184016
|
||
SPECIMEN COLLECTION |
||
Specimen type: |
Whole blood | |
Preferred collection container: |
||
Alternate Collection Container: |
Lavender-top (K2 EDTA) microcollection tube
2 mL pink-top K2 EDTA tube
|
|
Specimen required: |
TUBE: 2 mL EDTA lavender-top tube minimum 1.6 mL of whole blood OR EDTA microcollection tube with 250-500uL of whole blood AND SLIDES: Off-campus laboratory: Two-three blood smears are to accompany the sample. They must be labeled with two (2) patient identifiers and made within eight (8) hours of collection AND HISTORY: A brief history is entered into EPIC. The EPIC form is to accompany the blood sample to the Hematology Lab. site. |

Test includes: |
CBCD and Schistocyte interpretation by technologist | |
Methodology: |
Manual Microscopy |
|
Synonyms: |
Slide review for hemolysis, fragments
|
|
Clinical significance: |
Schistocytes are fragments of red blood cells produced by extrinsic mechanical damage within the circulation. The detection of schistocytes is an important morphological clue for diagnosis of hemolytic anemias. | |
