Test ID: HPFH
Hemoglobin F, Red Cell Distribution, Blood
Specimen Type 
Describes the specimen type needed for testing
Whole Blood EDTA
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Container/Tube: Lavender top (EDTA)
Specimen Volume: 3 mL
Additional Information:
1. Patient's age and sex are required.
2. Indicate the percent of hemoglobin F. If this is not indicated, we will perform HBF/8269 Hemoglobin F, Blood. If HBF/8269 Hemoglobin F, Blood gives normal results, HPFH/8270 Hemoglobin F, Red Cell Distribution, Blood will not be performed.
3. Indicate the reason for testing.
4. For information on thalassemias and appropriate test ordering, see Thalassemia Tests in Special Instructions.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
0.5 mL
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis | Mild reject; Gross reject |
| Lipemia | Mild OK; Gross OK |
| Icterus | NA |
| Other | NA |
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
| Specimen Type | Temperature | Time |
|---|---|---|
| Whole Blood EDTA | Refrigerated | 10 days |
