How is the icterus grade determined?

To assess the icterus grade, doctors first look very carefully at the skin and eyes. The degree of yellowing gives clues about how high the bilirubin level in the blood is. Doctors look at whether the yellowing is only visible in the eyes, or whether the face, the trunk, or even the limbs are also affected. The further the yellowing spreads, the higher the bilirubin level in the blood usually is.

In addition to this visual assessment, the bilirubin level can also be measured precisely in a laboratory. The visual judgement, that is the icterus grade, remains an important guide, especially during the first examination.

What can cause a raised icterus grade?

A raised icterus grade is not a condition in itself. It is a symptom that can point to various problems in the body. Common causes include liver diseases such as hepatitis, liver cirrhosis, or tumours. Problems with the bile ducts, for example due to stones or inflammation, can also play a role. Sometimes the cause is an excessive breakdown of red blood cells, for instance in certain blood disorders.

In rare cases, icterus can also occur in newborns. Here, a mild yellowing in the first few days of life is often harmless and usually goes away on its own. However, a strong or long-lasting icterus grade in babies should always be checked by a doctor.

Is a high icterus grade dangerous?

Many people are alarmed when they notice a clear yellowing in themselves or a family member. A pronounced icterus grade is always a warning sign that points to a problem in the body's metabolism or organs. How serious the situation is depends on the underlying cause.

Sometimes a temporary, easily treatable condition is behind it. In other cases, it can be a serious problem that requires prompt medical investigation and treatment. A doctor's examination is especially important when intense yellowing appears suddenly, or when there are additional symptoms such as stomach pain, fever, or strong feelings of being unwell.

What happens after a raised icterus grade is identified?

When a raised icterus grade is found, targeted tests usually follow. These include blood tests to check liver values and bilirubin levels. Ultrasound scans of the abdomen help to assess the liver and bile ducts more closely. Depending on the results, further tests may be needed, such as specialist laboratory analyses or imaging procedures.

Treatment always depends on the cause of the icterus. If, for example, a gallstone is blocking the flow, a procedure may be necessary. For liver inflammation or other conditions, different therapies are used. The aim is always to address the cause and bring the bilirubin level back down.

What should be kept in mind in everyday life?

Anyone who notices a yellowing of the skin or eyes should not ignore it. Even if the cause is sometimes harmless, a pronounced icterus grade can point to serious health problems. It is therefore advisable to see a doctor early to find out the cause and, if necessary, to start suitable treatment quickly.

Assessing the icterus grade is an important step in determining how severe icterus is and in monitoring how things develop. With targeted testing and treatment, many causes can be managed well and complications can be avoided.
