Siemens Healthcare Diagnostics, Deerfield, Ill, has introduced the LOCI (luminescent oxygen channeling assay) folate, LOCI B12, and LOCI ferritin tests for use on the Dimension Vista 1500 Intelligent Lab system, an ultra-integrated chemistry analyzer.

The tests are used by physicians to diagnose and monitor anemia in patients.

Anemia is generally defined as a decreased amount of healthy red blood cells in the circulation or an abnormally low concentration of hemoglobin, which is necessary to carry oxygen throughout the body. It is estimated to affect up to 30% of the population worldwide. Vitamin B12 deficiency anemia, folic acid deficiency anemia, and iron deficiency anemia are among the most commonly diagnosed anemias.

The company offers health care providers a broad range of diagnostic products and services for diagnosing medical conditions, monitoring patient therapy, and providing health care.
