| Reticulocyte Count (LAB001335) | |
|---|---|
| Test Mnemonic: | RETIC
|
| Specimen Requirements: | |
| Test Included: | Reticulocyte percent, absolute count, and immature retic fraction (IRF), Reticulated Hemoglobin Content (RET-He)
|
| Collection: | Routine venipuncture; Collect in EDTA (lavender tube). Micro-collection is acceptable. The specimen should be collected to the appropriate fill volume stated on the collection tube. The minimum volume required is 90% of the stated tube volume.
|
| Container: | EDTA (lavender tube). Micro-collection is acceptable. |
| Storage/Transport: | Room Temperature 8 hours. If testing cannot be completed within 8 hours sample must be refrigerated at 2-8° C.
|
| Stability: | Stable Refrigerated for 48 hours.
|
| Causes for Rejection: | Clotted or presence of fibrin, QNS (quantity not sufficient/underfilled), overfilled, gross hemolysis, samples drawn above IV line or contaminated with IV fluid, Mislabeled or underlabeled, incorrect storage temperature, stability exceeded, incorrect anticoagulant.
|
| Reference Range: | By report (reports may vary based on instrumentation, patient age and sex)
|
| Turnaround Time: | STATS: 1 hour. Routine: 4 hours.
|
| Methodology: | Flow Cytometry.
|
| Performed: | Samples are accepted 24 hours per day at Sample Management, CSW 7.412.
|
| Clinical Indication: | Assess rate of red cell production; effective versus ineffective erythropoiesis. RET-He detects changes in iron status.
|
| CPT 4 Code: | 85045

| Note: |
|
| When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent. | |
