Alternate Collection Container: |
Other size blue-top (3.2% sodium citrate) tubes (e.g., 1.8 mL, 4.5 mL)
|
|
Specimen required: |
2.7 mL blue-top (sodium citrate) tube. (ONLY for patients where the platelets clump in EDTA anticoagulant). Do not warm tubes or place in heel warmer. | |

TEST DETAILS |
||
Reference interval: |
140-400 K/uL | |
Critical values/courtesy alerts: |
PLT <=20 and >=1000 K/uL | |
Additional information: |
Patients who still show clumped platelets will receive an estimate only (low, adequate, high). Deliver to Hematology as soon as possible. Do not warm tubes. Do not place in heel warmer | |
CPT code(s): |
85049 | |

Test includes: |
Quantitative determination of platelets. | |
Methodology: |
Electronic resistance detection enhanced by hydrodynamic focusing and flow cytometry |
|
Synonyms: |
PLT Quantitative Platelet Count PLTBL
|
|
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. | |
