|
||
SPECIMEN COLLECTION |
||
Specimen type: |
Whole blood | |
Preferred collection container: |
||
Alternate Collection Container: |
6 mL pink-top K2 EDTA tube
|
|
Special notes: |

| SPECIMEN PROCESSING |
||
Specimen processing instructions: |
Send unspun blood collection immediately to testing laboratory. The blood must be received within 90 minutes of collection. | |
Transport temperature: |
Room temperature (15-30°C). Transport immediately via pneumatic tube system to the laboratory after collection. | |
Specimen stability: |
Testing must be performed within 90 minutes of collection if stored at room temperature (15-30°C). Refrigerate the specimen upon arrival into the laboratory. Specimen may be stored at 2-8°C for up to 4 hours. | |
Rejection criteria: |
Specimens stored or transported at incorrect temperature, frozen, stability limits exceeded, improper collection tube used, insufficient volume, improperly labeled/identified specimens (2 identifiers are required). The test is not intended for patients with the following conditions: <3 months or >17 years of age; pregnant women; active inflammatory disease; congenital or acquired immune deficiency; chronic fungal or parasitic infection; infection with human immunodeficiency virus (HIV); Hepatitis B virus (HBV); Hepatitis C virus (HCV); infection with active tuberculosis (TB); significant trauma or burns in the last 7 days; patients that have undergone major surgery in the last 7 days; or active malignancy. | |
