Toe brachial index - left   77617-9

LOINC Code


LOINC code77617-9
nameToe brachial index - left
descriptionThe reading is derived in order to determine the severity of peripheral arterial disease present in a lower extremity. The test is performed using a small blood pressure cuff that is fitted around a toe along with a photoplethysmograph (PPG) infrared light sensor. The resultant toe brachial index (TBI) is generated using the systolic blood pressure readings from the arm and toe.

propertyPresRto  =  Pressure Ratio
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemPeripheral vascular system
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
