What is a trabeculectomy? A trabeculectomy is a glaucoma operation usually done under local anaesthetic, via an injection beside the eye. It aims to reduce eye pressure caused by glaucoma, which can slowly damage - and even cause permanent loss of - eyesight, by draining fluid out of the eye.       Why would someone need a trabeculectomy?    Th

What is analysed?Trace elements are a subset of essential minerals in the body that play an important role in various physiological functions, including the production of enzymes and hormones.Trace elements include:chromiumcopperfluorideiodineironmanganesemolybdenumvseleniumvcincThe trace elements test measures the level of trace elements, mainly in the blood but also in urine or other bodily flui

What is tracheal stenosis?Tracheal stenosis refers to a narrowing of the trachea, more commonly referred to as the windpipe. It occurs as a result of the formation of scar tissue in the trachea, or due a malformation of the cartilage in the trachea. The narrowing, if mild in nature, may not be noticed, but if the narrowing becomes more severe (over 50 per cent of the airway) then complication

What is transcranial magnetic stimulation (TMS)?Transcranial magnetic stimulation (TMS) is a non-invasive procedure used to treat depression and other forms of mental illness, including post-traumatic stress disorder (PTSD). TMS uses magnetic fields to stimulate nerve cells in the brain.

What is transcutaneous electrical nerve stimulation (TENS)? Transcutaneous electrical nerve stimulation (TENS) involves the use of small, low-voltage electrical currents to treat pain. The electrical currents are delivered from a battery-powered TENS machine which patients are given to use at home. The TENS machine is small and includes leads which are connected to sticky pads called electro

What is analysed? Transferrin and iron-binding capacity are crucial components in assessing the body's iron status. Transferrin is a protein that binds to iron, facilitating its transport through the bloodstream. Iron-binding capacity measures the amount of iron that can be bound by transferrin, reflecting the body's ability to manage iron.   What does the result mean? T
