A Brief Introduction to the Carboxyhaemoglobin Test

Carboxyhemoglobin, or COHb, refers to the binding of carbon monoxide to the iron-containing protein in red blood cells called hemoglobin. This occurs when you breathe in carbon monoxide. When exposed to this gas, it enters blood flow and binds to hemoglobin, reducing the amount of oxygen your body can use.

What is carboxyhaemoglobin?

The Chughtai Laboratory in Lahore does important work in blood testing. It’s a great service that has helped many patients and their families, including mothers-to-be who needed a quick heart rate test or young children who had been hospitalized. Chughtai lab Lahore has received multiple accolades for its commitment to quality healthcare, and it is one of several services designed by doctor

What is the carboxyhaemoglobin test?

Also known as a carbon monoxide blood test, carboxyhaemoglobin is a method of testing for exposure to carbon monoxide. This can be caused by smoking or inhaling second-hand smoke and also by car exhaust. Exposure can lead to several health problems, including headaches, difficulty breathing and heart palpitations. The carboxyhemoglobin test measures levels of COHb (carbon monoxide hemoglobin) in the blood.

How is carboxyhemoglobin measured?

A blood test is used to determine levels of carboxyhemoglobin in your bloodstream. The concentration of carbon monoxide in your blood is measured through a red blood cell (RBC) count, and hemoglobin concentrations are measured directly. According to Chughtai Lab rates list, hemoglobin and RBC are vital for delivering oxygen throughout your body. When you breathe in carbon monoxide, it bonds with hemoglobin and prevents it from transporting oxygen around your body.

What are the symptoms of CO poisoning?

When there is exposure to carbon monoxide at low levels, some people don’t experience any symptoms. However, if exposed for long periods, you may experience dizziness, nausea, weakness, and loss of appetite. It can also cause flu-like symptoms such as a headache and tiredness that will last several days after exposure.

Who should get tested for CO poisoning?

Every year, thousands of people around the world die from carbon monoxide poisoning. Yet few people outside of medical professionals are even aware that CO can be fatal. If you’re concerned about your exposure levels, booking an online lab test in Pakistan might be a good idea. You can take comfort in knowing that even if you discover high levels of CO in your blood, simple treatment is available and can greatly improve your chances of survival.

What if I am pregnant or breastfeeding?

If you are pregnant or breastfeeding, you may have high levels of COHb. Talk to your doctor before having an elevated COHb test. Also, if you take oral iron supplements while pregnant or breastfeeding, ask your doctor if it's safe to study elevated COHb levels, as blood iron levels may need to be monitored more closely during pregnancy and lactation.

The level of carboxyhemoglobin (COHb) in newborns is lower than that of adults and children due to low haemoglobin levels, which increases CO transport time from peripheral blood vessels into red blood cells.

The half-life of carboxyhemoglobin in the blood is approximately 4.6 hours, meaning it takes approximately 14.4 hours for half a given amount of COHb to be metabolized by various biochemical reactions after exposure.

Where can I get more information on CO testing?

The chughtai test report is a lab test you can get done to determine if there are CO levels in your blood. The chughtai blood test is one of several ways doctors can measure carbon monoxide.
