The most common test for jaundice is a bilirubin blood test, which measures the level of bilirubin in the blood. Bilirubin is a yellow pigment produced when red blood cells break down. High bilirubin levels can cause jaundice, a condition that makes the skin and whites of the eyes appear yellow.
The bilirubin blood test is used to:
- Check the health of your liver
- Look for the cause of jaundice
- Determine how well a treatment is working
Other tests that may be used to diagnose jaundice include:
- Transcutaneous bilirubinometry: A small device called a bilirubinometer shines light onto the baby's skin. The device analyzes how the light reflects off the skin to calculate the bilirubin level.
- Coombs' test: This test is used to detect antibodies that can cause red blood cell destruction.
- Physical examination: In most cases, a physical examination is enough to confirm a diagnosis of jaundice. The doctor will look for yellowing of the skin and whites of the eyes.
Jaundice is a common condition in newborns, especially premature babies. It is usually harmless and clears up within a few weeks. However, if jaundice is severe or persistent, it could be a sign of a more serious condition. If you are concerned about your baby's health, it is important to speak to your doctor.
In adults, jaundice can be caused by a variety of conditions, including liver disease, gallstones, and certain medications. If you experience jaundice, it is important to see your doctor to determine the cause and get appropriate treatment.
