Bypass surgery, also known as Coronary Artery Bypass Grafting (CABG), is a procedure to replace damaged or blocked arteries in the heart with blood vessels from another part of the body.

Patients with severe coronary artery disease, where the arteries are significantly narrowed or blocked, may need bypass surgery to improve blood flow to the heart.

A surgeon takes a healthy blood vessel from your leg, arm, or chest and connects it to the blocked coronary artery, bypassing the blocked section to improve blood flow.

Risks include infection, bleeding, heart attack, stroke, and reactions to anaesthesia, though serious complications are rare.

The surgery typically lasts between 3 to 6 hours, depending on the number of arteries being bypassed and the patient’s condition.

The Ionised Calcium test measures the level of free, biologically active calcium in the blood, which is crucial for various bodily functions.

It provides a more accurate assessment of calcium levels compared to total calcium tests, helping diagnose and manage conditions affecting calcium balance.

No special preparation is usually needed. Inform your healthcare provider about any medications or supplements, and follow any specific instructions given.

Results are typically available within a few hours to 1 day after the blood sample is processed.

The test helps diagnose calcium imbalances, parathyroid disorders, kidney dysfunction, bone health issues, and cancer-related hypercalcemia.

The procedure may involve making incisions to access the jawbone and using plates, screws, or wires to align and stabilize it.
