Hemoglobin and Red Blood Cell Electrophoresis (Serum/Plasma)

Published: August 9, 2026Updated: August 16, 2026

This test measures the types and amounts of proteins in your red blood cells, including hemoglobin variants, using electrophoresis. It helps identify conditions affecting red blood cell structure or function.

What This Test Measures

Electrophoresis separates proteins in your blood based on size and electrical charge. In this test, we analyze hemoglobin and red blood cell components to identify any abnormal patterns or concentrations that may indicate inherited or acquired blood disorders.

Why It’s Done

Your doctor may order this test if you have symptoms like fatigue, pale skin, unusual pain, or a family history of blood disorders. It’s also used to screen for conditions like sickle cell disease, thalassemia, or other hemoglobin-related issues.

How It Works

A small blood sample is drawn, and the serum/plasma is separated. Proteins are then placed on a gel and exposed to an electric current, causing them to move at different speeds. A specialized instrument detects and measures the distribution of these proteins.

Sample Collection

A needle is used to draw blood from a vein in your arm. The sample is processed to isolate serum or plasma for analysis. This process is quick and typically done in a clinical setting.

Reference range

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

Specimen: whole-blood

No special preparation required. Stay well hydrated.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal results may indicate inherited blood disorders (e.g., sickle cell anemia, thalassemia), metabolic issues, or other conditions affecting red blood cell proteins. Early detection can guide treatment and management strategies.

Frequently asked questions

What does an abnormal result mean?
An abnormal result may suggest an inherited blood disorder, such as sickle cell disease or another hemoglobinopathy. It could also point to conditions affecting red blood cell production or structure. Your doctor will discuss the findings with you and may recommend further testing or treatment.
How long does it take to get results?
Results are usually available within 1 to 3 business days, depending on lab processing times. Your healthcare provider will contact you once they are ready for review.
Can I eat or drink before this test?
You can eat and drink normally before this test, as it does not require fasting. However, follow any specific instructions your doctor or lab provides for your safety and accuracy.
