Included with every panel
Baseline labs come free with any panel you build.
Other tests
Absolute Blasts test
The absolute number of blasts (immature precursor cells) in blood, normally zero since these cells belong in the marrow. Included with every panel.

What it measures
Looks for blasts, very young blood cells that normally stay in your bone marrow, the soft tissue inside bones where blood is made. Usually none are found in the blood.
Why it matters for women
There’s nothing women-specific about this result. It’s part of the blood count included with every panel, a basic check that your bone marrow is working normally. Finding blasts is uncommon and can lead to more testing, not an answer on its own.
You might check it if…
- a past blood count showed unusual white cell results
- you bruise or bleed easily without a clear reason
- you get frequent infections, fevers or unusual tiredness
What your result may mean
High Absolute Blasts: what it may mean
A high or measurable absolute blast count may be abnormal and can point to leukemia or another bone marrow disorder that may need urgent evaluation. Blasts are very young blood cells that belong in the marrow, so finding them in the blood may mean the marrow isn't working normally. Less frequently, a few can appear while the marrow recovers from severe infection or chemotherapy, or after growth-factor medicines. Some people may notice tiredness, fevers, easy bruising or bleeding, and others may feel fine. This count can't give an answer on its own, so a clinician may order a blood smear and more testing.
Low Absolute Blasts: what it may mean
A low absolute blast count, or zero, may be the normal result, because these very young cells can stay inside the bone marrow until they mature. This is the result a clinician may expect to see. It can't rule out every blood or marrow condition, since some can appear in other parts of the blood count first. With unusual bruising, ongoing fevers or deep tiredness, your red cells, platelets and other white cells can give a fuller picture.
