What it measures
Counts promyelocytes, very early white blood cells that belong in your bone marrow, the soft tissue inside your bones where blood cells are made. Normally none are found in the blood.
Why it matters for women
None is the expected result, and that’s the same for women and men. Promyelocytes in the blood are uncommon, but they can be a sign that your bone marrow is under heavy strain or isn’t making blood cells normally. Any found are worth talking through with your clinician soon.
You might check it if…
- you bruise easily or bleed more than usual
- you’ve felt unusually tired, pale or short of breath
- you’ve been getting infections more often than usual
- a past blood count showed unusual white cells
What your result may mean
High Absolute Promyelocytes: what it may mean
A high or measurable promyelocyte count can be a sign of severe bone marrow stress or leukemia, and it may need prompt review. These very early white cells can stay in the marrow, so finding them in the blood may mean the marrow is under heavy strain or isn't making blood cells normally. A severe infection or recovery after chemotherapy can also release a few. One rare form, acute promyelocytic leukemia, can cause serious bleeding and may need urgent care. Warning signs can include easy bruising, bleeding gums, unusually heavy periods, fevers or tiredness.
Low Absolute Promyelocytes: what it may mean
A low or zero promyelocyte count may be what a clinician expects, since none may appear in healthy blood. Promyelocytes are a very early stage of white blood cell, and they can stay deep in the bone marrow until they grow. The same can be true for women and men. This result can't check everything about your marrow, so your hemoglobin, platelets and other white cells can add to the picture.
