- Transport to laboratory as soon as possible
Whole Blood with Fluoride
Container Type | Container Size | Specimen Volume |
---|---|---|
PreferredGray tube (Sodium Fluoride) |
2 mL | 2 mL |
AlternateGray tube (Sodium Fluoride) |
Micro sample tube | 1 mL |
Stability
Refrigerated - 24 hour(s)
Room temperature - 24 hour(s)
Specimen Preparation
- Mix by gentle inversion immediately after collection
- Transport to the lab immediately after collection
- Do not spin and separate gray top tubes
Reasons for Rejection
- Gross hemolysis
- Not received at proper temperature
- Not received within specified time frame
Comments
Analysis of testing collected in Sodium Fluoride is limited to glucose and lactate only. No other routine analytes are possible. All glucose samples not separated from cells within 1 hour must be drawn in a gray top tube (if delayed transport to Laboratory is a possibility, use gray-top tube). Patient should fast for at least 8 hours without caloric intake.
