ABI/ASI Testing

ABI/ASI testing is a proven non-invasive diagnostic service which can measure blood pressure, pulse pressure and detect arrhythmias or irregular heartbeats.

ABI/ASI testing produces an Arterial Stiffness Index (ASI) from the brachial artery which is then correlated with the stiffness of the other arteries. The Ankle Brachial Index (ABI), a reliable test for peripheral artery disease (PAD) is performed in less than 15 minutes.

The importance of pre-symptom screening with ABI/ASI testing can not be overstated. Only too often the first symptoms to appear are heart attack or stroke. Current research confirms the effectiveness of this painless procedure.

TLC DIAGNOSTICS ABI/ASI TESTING PROVIDES THE FOLLOWING: 

• Blood pressure (systolic, diastolic, pulse)

• Pulse Pressure (difference between systolic and diastolic)

• Detection of arrhythmias or irregular heartbeats.

• Arterial Stiffness Index (ASI) which produces a number correlating to either normal, moderate stiffness or a stiff artery. The ASI measurement utilizes a method known as computerized oscillometry where proprietary algorithms are applied to the slope of the oscillometric blood pressure curve to obtain the ASI.

• Ankle Brachial Index (ABI), a diagnostic test for detecting PAD and other conditions is also measured by computerized oscillometry. Systolic pressures in the upper arms and legs are measured while the patient is in the supine position. The highest systolic pressure from either upper arm is divided into each ankle systolic pressure to calculate the ABI ratios. This ratio is a simple diagnostic test for arteriosclerosis in either leg.

• An optional Framingham Risk Score provides a 10 year Risk Assessment for a coronary event based on blood pressure, age, sex, lipid scores (Total cholesterol, LDL & HDL).
