What is a Traditional Blood Test?

Blood tests are an essential segment of your health care. They can measure or examine cells, chemicals, and proteins in the blood, which helps doctors with various purposes, from generating lists for treatments to identifying problems before they become worse. They are also helpful to:

• Help find out what's wrong with some chronic diseases

• Keep an eye on a long-term illness or conditions, like kidney disease or high cholesterol

• Find out if the medication used in treating a disease is working.

• Check the health of your organs.

• Accurately identify haemorrhaging or blood clotting abnormalities.

• Check to see if your immune system is struggling to fight off infections.

What happens during a blood test?

A blood test usually involves removing blood from the blood vessels on the arms. It's usually a good place to take a blood sample at the inside of the elbows and wrists where veins are relatively close to the skin's surface. A tight band (tourniquet) can be placed around the upper arms. The band compresses your wrist and slows down your circulation to make your veins more visible.

How will my blood be taken?

The tourniquet is tightly held around your upper arm so the blood flow in the elbows is positioned at the surface and can be identified easily when needed. Vascular surfaces are scrubbed using a clean alcohol wand. A tiny needle can enter your vein and a tiny blood vessel will connect. Blood flows through the bottle and the needle is taken out once it's filled.

What happens to my blood after the test?

Generally the bottle contains little amounts of an agent to help stop blood clots in your tube and make it more precise for laboratory testing. The bottles are labelled with your name and birth date and the tops have different colours depending on the type of test the blood is taken for. It's time for analysis.

Preparing for a blood test

Before you have a blood test, it’s important to be properly prepared. If possible, avoid drinking alcohol or caffeinated beverages the day before your test and make sure to get enough rest. Additionally, eating breakfast can help to ensure accurate results because your body may not be producing the necessary antibodies if you are fasting for too long. Be sure to wear clothing that is easy to remove and that you feel comfortable in. Finally, if you have taken any medications recently, make sure to let your doctor know—some drugs can affect test results.

Blood Testing and Diabetes

Blood testing and diabetes are closely related because monitoring blood glucose levels on a regular basis is crucial to managing the condition. For people with diabetes to monitor their health, ensure that they have control over their diabetes, and guard against potential complications, the relationship between diabetes and blood testing is essential.

Doctors can measure blood glucose levels using blood tests, which gives them a better idea of how well the diabetes management strategy is working. Doctors can use this data to determine whether a patient needs to change their medication, diet, or exercise routine. Blood tests are also used to determine whether a person has diabetes and to track their risk of developing complications like heart disease and stroke. 

Blood Testing and Cholesterol

An effective way to keep track of your general health and wellbeing is through blood testing and cholesterol. It's crucial to routinely check your cholesterol level because it can cause a number of serious medical problems, such as heart disease and stroke. The most precise method for measuring and monitoring changes in your cholesterol levels over time is through blood tests. Read more on: High cholesterol: Symptoms, causes and levels.
