Unidentified Cells in Blood (Manual Count)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like unexplained fatigue, frequent infections, unusual bruising, bleeding, or if they suspect a blood disorder. It could also be part of routine monitoring for conditions like leukemia, lymphoma, or other hematologic diseases.

What to Expect Before the Test

No special preparation is typically needed. You may have a small needle inserted into your arm or hand to draw a small amount of blood. The process is quick and usually painless. If you’re on blood thinners or have a history of bleeding issues, let your provider know.

What the Results Mean

The test counts and identifies any abnormal cells in your blood sample. Results are qualitative (yes/no) rather than numerical, so your provider will interpret the findings based on your clinical picture and symptoms. High or unusual cell counts may prompt further testing or treatments.

Common Conditions Linked to Abnormal Blood Cells

Conditions such as leukemia (cancer of blood cells), lymphoma (cancer of immune cells), infections (e.g., mononucleosis), or inherited blood disorders (e.g., sickle cell anemia) may show abnormal cells in blood tests. Other causes can include autoimmune diseases or exposure to certain toxins.
