What is Hs ESR?
The high‑sensitivity erythrocyte sedimentation rate (Hs ESR) is a laboratory test that measures how quickly red blood cells settle at the bottom of a vertical tube over one hour. It is a non‑specific indicator of inflammation, infection, or tissue injury. Because the test is simple, inexpensive, and widely available, it is often ordered as a first‑line screening tool in clinical practice.
How the test is performed
Blood is drawn into a tube containing an anticoagulant, usually sodium citrate. The tube is placed upright at a controlled temperature, and the distance (in millimetres) that the red cells have fallen after 60 minutes is recorded. The result is expressed as mm/hr. A “high‑sensitivity” method uses a smaller blood volume and tighter temperature control, providing more consistent results for values that are near the normal range.
Understanding a result of 60 mm/hr
When the report reads Hs ESR 60, it means that the red cells settled 60 mm in one hour. This value is considerably above the typical upper limits of normal (usually 20 mm/hr for men and 30 mm/hr for women, though reference ranges may vary by laboratory).
What does a high value indicate?
Because ESR does not identify a specific disease, a result of 60 mm/hr signals that an inflammatory process is active somewhere in the body. The test is especially useful for:
- Detecting acute or chronic inflammation
- Monitoring disease activity in known inflammatory conditions
- Assessing response to treatment
It is important to interpret the result alongside clinical findings, other laboratory markers (such as C‑reactive protein), and imaging studies.
Common conditions associated with Hs ESR 60
Several disorders can produce an ESR of 60 mm/hr or higher. The most frequent include:
- Rheumatoid arthritis – active joint inflammation often raises ESR dramatically.
- Systemic lupus erythematosus – flares are typically accompanied by elevated ESR.
- Infections – bacterial infections, especially those causing sepsis, can push ESR into the 60‑plus range.
- Temporal arteritis – a classic cause of markedly high ESR in older adults.
