The question "How to check ESR in CBC report?" is slightly misleading. A Complete Blood Count (CBC) and Erythrocyte Sedimentation Rate (ESR) are separate tests, although they are often ordered together. Therefore, you won't find the ESR result within the CBC report. Instead, you'll find it on a separate lab report. Here's how to understand and interpret the ESR result:
Understanding the ESR Test
The Erythrocyte Sedimentation Rate (ESR), also known as a sedimentation rate or "sed rate," measures how quickly red blood cells (erythrocytes) settle at the bottom of a test tube. This test indirectly measures the degree of inflammation in the body.
- The Process: According to the reference provided, a blood sample is taken from a vein, placed in a tall, thin tube, and allowed to stand. The rate at which red blood cells fall to the bottom is then measured.
- Inflammation and ESR: Inflammation causes red blood cells to clump together. These clumps are heavier and settle faster. Therefore, a higher ESR indicates a greater degree of inflammation.
Locating the ESR Result
- Separate Report: Look for a separate laboratory report specifically labeled "Erythrocyte Sedimentation Rate" or "ESR." It will likely be provided alongside your CBC report.
- Patient Information: Verify that the report includes your name, date of birth, and other identifying information to ensure it's your result.
- ESR Value: The report will show a numerical value for your ESR, usually expressed in millimeters per hour (mm/hr). For example, "ESR: 20 mm/hr."
Interpreting the ESR Result
The normal ranges for ESR can vary slightly depending on the laboratory and the method used. However, general guidelines are:
| Group | Normal Range (mm/hr) |
|---|---|
| Men under 50 | 0-15 |
| Men over 50 | 0-20 |
| Women under 50 | 0-20 |
| Women over 50 | 0-30 |
| Children | 0-10 |
It's important to note that these are just general guidelines. Your doctor will interpret your ESR result in the context of your medical history, physical examination, and other test results.
- Elevated ESR: A high ESR suggests inflammation in the body. It can be caused by various conditions, including infections, autoimmune diseases, cancers, and other inflammatory conditions.
- Normal ESR: A normal ESR does not always rule out disease. Some people with inflammatory conditions may have normal ESR levels.
- Consultation: Always discuss your ESR result with your doctor for proper interpretation and diagnosis. The ESR test is not specific and cannot diagnose any particular condition. It only indicates the presence of inflammation.
