PreciS™-B Blood Pressure Monitor

Blood pressure is the force of blood against your artery walls. When this pressure is consistently too high, it’s a condition known as hypertension. Often called “the silent killer,” hypertension typically has no symptoms but can cause serious long-term damage to your heart, kidneys, and blood vessels, leading to stroke or heart attack.

Blood pressure fluctuates depending on time of day, activity level, and emotions. For accurate readings, measurements should be taken under resting conditions and on several occasions. Normally, blood pressure will increase if:

1) Blood volume rises due to excess salt intake, which causes the body to retain more water.

2) Blood vessels become more rigid as a result of atherosclerosis, where fatty substances are deposited in the vessel walls.

Early management of blood pressure is key to preventing serious health issues in the future.

PreciSTM – C Cholesterol Monitoring System uses a timed-endpoint method to measure the Total Cholesterol (CHOL), High Density Lipoprotein (HDL) and Triglyceride (TRIG) concentrations in whole blood, serum or plasma. The concentration of Low Density Lipoprotein (LDL) is calculated by the values of CHOL, TRIG and HDL. The system monitors the change in light absorbance at a fixed time interval. The change in absorbance is directly proportional to the concentration of lipid in the specimen.

CHOL: In this reaction, a cholesterol specific enzyme hydrolyzes cholesterol esters to free cholesterol and fatty acids. The free cholesterol is oxidized to cholestene-3-one and hydrogen peroxide by another enzyme. Hydrogen peroxide and a substrate is then further catalyzed by a 3rd enzyme to produce a coloured product.

HDL: HDL in the specimen is separated (from chylomicrons, VLDL and LDL) within the test device and then determined enzymatically as CHOL.

TRIG: Triglycerides in the specimen are enzymatically hydrolyzed to glycerol and free fatty acids. Next, a sequence of three coupled enzymatic steps causes the oxidation of a substrate to form a coloured product.

LDL: LDL is calculated when the concentration of TRIG in the specimen is equal or lower than 400 mg/dL. The following equation is use: CHOL – HDL – TRIG/2.2 (mmol/L) or CHOL – HDL – TRIG/5 (mg/dL)
