Blood tests used to try to detect a disease when there is little or no evidence of a suspected disease (http://www.bloodindex.org/Glossary.php). These tests are rapid tests where the results are available within 60 seconds to 30 minutes. They can be done in consulting rooms, clinics, casualty or temporary facility as the monitors are small, lightweight and compact. A range of tests are available: White Bloodcell Count (WBC), Microalbumin (MAU) and Hemoglobin (Hb).
