Overview
Laboratory Tests
Laboratory findings consistent with the diagnosis of myelofibrosis include:[1]
Complete Blood Count
Peripheral Blood Smear
- Normochromic normocytic anemia
- Red cell poikilocytosis on blood film (tear-drop shaped RBCs)
- Nucleated red blood cells
- Presence of nucleated red blood cells suggests that immature cells are being released into the bloodstream in response to a very high demand for the bone marrow to produce new red blood cells.
- JAK 2 mutation on Val 617 Phe locus in 50%
- Raised levels of lactate dehydrogenase
- Raised neutrophil alkaline phosphatase score
TB testing
The patient with the myelofibrosis should be tested for Tuberculosis even if the patient doesn't manifest the symptoms of TB. There is strong evidence of myelofibrois improvement with the antituberculous treatment.
