Geisinger Epic Procedure Code: LAB2863
Geisinger Epic ID: 21195
|
||
SPECIMEN COLLECTION |
||
Specimen type: |
Whole blood | |
Preferred collection container: |
||
Alternate Collection Container: |
Lavender-top (K2 EDTA) microcollection tube
|
|
Specimen required: |
3 mL lavender-top (K2 EDTA) tube collected MUST be properly filled to at least 1.5 mL (half the fill volume of the tube). Lavender-top (K2 EDTA) microcollection tube MUST be properly filled to at least 250 uL (half the fill volume of the tube). |
|
| SPECIMEN PROCESSING |
||
Specimen processing instructions: |
Do NOT centrifuge. | |
Transport temperature: |
Room temperature (preferred) or refrigerated. | |
Specimen stability: |
Refrigerated: 72 hours. Room temperature: 24 hours. | |
Rejection criteria: |
Clotted, frozen, hemolyzed, overfilled, underfilled, or centrifuged samples. Specimens beyond stability limits. | |
TEST DETAILS |
||
Reference interval: |
140-400 K/uL | |
Critical values/courtesy alerts: |
PLT <=20 and >=1000 K/uL. | |
Additional information: |
Patient with clumped platelets will result an estimate only (decreased, adequate, increased). For EDTA platelet clumping, order platelet count for patients with platelet clumping (LAB2859), an additional blue-top (sodium citrate) tube is required. Potential related available add on testing includes: CBC with WBC differential (LAB1963), CBC(LAB1961), HGB (LAB2461), HCT (LAB2400) reticulocyte panel (LAB3006); blood smear interpretation by pathologist (LAB2832); immature platelet fraction (LAB2524) can only be added if sample is collected at testing laboratory; See individual test requirements. |

Test includes: |
PLT. | |
Methodology: |
Electronic resistance detection enhanced by hydrodynamic focusing and flow cytometry |
|
Synonyms: |
PLT Quantitative Platelet Count
|
|
Clinical significance: |
Both increases and decreases in the platelet count can point to abnormal conditions of excess bleeding or clotting. These bleeding or clotting disorders or bone marrow diseases require the determination of the number of platelets present and/or their ability to function correctly. | |
