Final answer:
Pre-operative tests such as electrolytes, glucose, liver function tests (LFTs), and thyroid-stimulating hormone (TSH) assessments are crucial in evaluating a patient's readiness for surgery and managing potential risks.
Step-by-step explanation:
Pre-operative testing can include a range of blood tests to ensure that a patient is fit for surgery and to prevent any unforeseen complications. Specific tests are performed based on the patient's history, the type of surgery, and any underlying medical conditions.
Electrolytes
Checking electrolytes is important because imbalances can affect heart, nerve, and muscle functions, which are vital during and after the surgery.
Glucose
The pre-operative check of glucose levels is critical, especially in diagnosing and managing diabetes mellitus. A glucose tolerance test may be used to determine if a patient has diabetes by assessing their blood-glucose levels after fasting and consumption of a sugary drink.
Liver Function Tests (LFTs)
Liver function tests assess the health of the liver by measuring levels of liver enzymes, metabolites, or products in the blood. These are particularly relevant if there's suspicion of liver or biliary diseases.
Thyroid-Stimulating Hormone (TSH)
Testing for Thyroid-Stimulating Hormone (TSH) is important where thyroid function is in question, as thyroid diseases can affect metabolism and recovery from surgery.
