“You could take an armful of blood and you couldn’t do that.” Instead, if your full blood count indicates that a certain blood cell is abnormally high or low, this may indicate infection, anaemia, or other more serious diseases. Depending on the results, the GP may then request more tests to confirm a diagnosis.
What does gray top mean?
A blood collection tube containing powdered sodium fluoride and/or potassium oxalate, which inhibits glycolysis; ‘gray tops’ are used for glucose tolerance testing because glycolysis in the red cells would cause false-low glucose, for measuring lactate—transported on ice—lactate tolerance.
What happens if you underfill a tube with blood?
Conclusions Underfilling of tubes leads to a higher proportion of blood aspirated with high velocity and relevant elevations in LD. This finding should be considered in cases of clinically implausible elevated LD activities.
How long is glucose stable in a gray top tube?
Gray tops contain potassium oxalate as anticoagulant and sodium fluoride as preservative. Sodium fluoride inhibits glycolytic enzyme enolase, which limits ex vivo consumption of glucose in the specimen. Therefore, glucose in the gray top is stable for up to 24 hours.
What additive is in a GREY top tube?
Gray-top tube: Contains sodium fluoride (a preservative) and potassium oxalate (an anticoagulant). Use: Sodium fluoride whole blood or plasma.

What is abnormal blood count?
Abnormal red blood cell, hemoglobin, or hematocrit levels may indicate anemia, iron deficiency, or heart disease. Low white cell count may indicate an autoimmune disorder, bone marrow disorder, or cancer. High white cell count may indicate an infection or reaction to medication.
What blood tests detect heart problems?
The most common types of blood tests used to assess heart conditions are:
- Cardiac enzyme tests (including troponin tests) – these help diagnose or exclude a heart attack.
- Full blood count (FBC) – this measures different types of blood levels and can show, for example, if there is an infection or if you have anaemia.
Should I be worried about abnormal blood test?
Abnormal blood counts may indicate an underlying disease, but they are often treatable. Always check with your healthcare provider about what your blood test results mean.

- Coagulation Tubes (Blue-Top Tubes)
- Serum Tubes without Clot Activator or Gel (Red-Top tubes)

- Heparin Tubes (Green-Top Tubes)
- EDTA Tubes (Lavender-Top Tubes)
What happens if a gray tube is underfilled?
If tubes are underfilled, the blood:anticoagulant ratio may result in hemolysis. Avoid underfilling tubes by having an ample supply of tubes of various capacities.
