ESR Stat Plus is an automated blood sedimentation rate analyzer from HemaTechnologies. It features proprietary EZ-SAFE self-sealing analysis tubes, and can deliver three sed rates in five minutes. ESR Stat Plus requires only 25 microliters of blood, making it efficient and especially appropriate for pediatric patients. What is a sed rate? Sed rate is short for erythrocyte sedimentation rate, or ESR. This is a type of blood test, used primarily to detect inflammation. How effective is ESR? The test itself is non-specific, and is usually done along with other tests. An ESR test can indicate whether or not there is inflammation, but does not explain what is causing that symptom. Which conditions cause inflammation? Inflammation is a relatively common symptom. Cancers, autoimmune diseases, and infections often cause inflammation. Some specific inflammatory illnesses including temporal arteritis, systemic vasculitis, and polymyalgia are diagnosed through sed rate tests, in conjunction with other tests. How does the test work? To determine a sed rate, blood is put in a long tube. The red blood cells, or erythrocytes, settle to the bottom over time. If inflammation is present, it can cause the red cells to form clumps. These are heavier than individual cells, so they sink faster. A sed rate test measures how far the cells move in a set amount of time. The ESR Stat Plus delivers results in a few minutes, while conventional test methods can take one hour.

A convenient desktop device, the ESR Stat Plus is an automated medical instrument that provides erythrocyte sedimentation rate (ESR) readings quickly. The ESR Stat Plus readings are designed to detect and measure inflammation present in the body. Typically, “sed” rate testing, which involves measuring the descent of red blood cells in a vertical tube, takes considerable time. The ESR Stat Plus, however, speeds the process dramatically. The body’s level of inflammation is determined by the distance the red blood cells travel. Measuring the distance in a stored tube is a process that can take up to one hour, while the ESR Stat Plus can read three blood samples in five minutes. In addition, the samples can be much smaller than those required for conventional testing. Sed rate testing is typically ordered if a medical provider suspects a patient has polymyalgia rheumatica, rheumatoid arthritis, giant cell arteritis, etc. Sed rate tests are often used along with the C-reactive protein test. |
