Instructions: Track your blood counts
This tracker can help you organize your blood test results, so that you can discuss your results with your healthcare provider and compare them with your target blood counts. Testing your blood counts regularly is critical to managing the progress of your PV.
- Use your laboratory blood test results sheet from your most recent blood test to enter your values.
- For each blood count, use your device keyboard or number pad to input the laboratory value from your laboratory blood test results.
Your haematocrit (HCT), which is the proportion, by volume, of blood that is made up of red blood cells, is a ratio and is measured as a fraction out of 1 (for example, 0.45). The unit of measure for your haemoglobin (Hgb) level is g/dL. The unit of measure for both your platelet count and your white blood cell, or leukocyte, count is x 109/L. - With the calendar function, select the date your blood was drawn for your laboratory test.
- Click or tap the “Save blood counts” button when finished and confirm the values entered. This will then open a page displaying important questions regarding blood counts to discuss with your healthcare provider, as well as options to move to the next portion of the tracker.

What would you like to do next?
Actively track your blood counts and discuss how they compare with your target blood levels
Your blood counts, particularly haematocrit (HCT), white blood cells (WBCs), haemoglobin (Hgb), and platelets, offer important information about the status of your polycythaemia vera (PV). Talk to your healthcare provider about your results after each blood test and discuss how your individual blood results compare with your target blood levels.
The following questions may help you discuss your blood counts with your healthcare provider:
- What are my target levels for HCT and WBCs?
- What are my management options if my HCT or WBCs are above the target level?
- What other factors might influence my blood test results?
- Why is it important to monitor my blood cell counts to keep PV controlled?
- Why is it important to know if my blood cell counts are above the target level?
