Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like fatigue, pale skin, unusual bruising, or unexplained bleeding. It’s also used when blood tests suggest possible blood disorders, such as thalassemia, sickle cell disease, or other inherited or acquired conditions affecting RBCs.

What to Expect During the Test

This is a blood sample test, typically drawn from a vein in your arm. The sample is sent to a lab for microscopic examination of RBCs. No special preparation is needed, but inform your provider about any medications or recent blood transfusions.

Common Conditions Linked to Dysmorphic RBCs

Dysmorphic RBCs can appear irregular in size, shape, or color. Conditions that may lead to these changes include hereditary blood disorders (e.g., spherocytosis, elliptocytosis), infections, autoimmune diseases, or exposure to certain toxins.

What the Results Mean

Results are qualitative (descriptive) rather than numerical. If abnormal RBCs are found, your provider will discuss next steps, which may include further testing or monitoring.

Reference range

Adult males: 4.2-5.9; Females: 3.8-5.1 x 10^12/LN/A

Specimen: urine

No special preparation required. Stay well hydrated.

Frequently asked questions

Will I need to prepare for this test?
No special preparation is required. However, avoid eating or drinking anything (except water) for 2–4 hours before the blood draw if instructed by your provider.
How long will it take to get my results?
Results are typically available within 1–3 business days, depending on lab processing times. Follow-up with your provider to discuss findings.
Can I ask for a different type of RBC analysis?
If you have specific concerns, discuss them with your provider. While this test focuses on qualitative morphology, some labs offer quantitative tests (e.g., mean corpuscular volume) for additional insights—your provider can clarify options.
