Specimen Collection Manual and Test Catalog

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).

The test is indicated for use in pediatric patients (>3 months to <18 years of age) presenting to the emergency department, with suspected acute bacterial or viral infections, who have had symptoms and fever within the last 7 days. The test is currently only offered at Geisinger Medical Center.

Room temperature (15-30°C). Transport immediately via pneumatic tube system to the laboratory after collection.

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.

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.
