<s>[INST] What tests will I need? [/INST] Doctors may do tests such as:

Blood tests to check your liver and see if the liver is damaged
Imaging tests such as ultrasound, CT (computed tomography) scan, or MRI (magnetic resonance imaging)
Sometimes, liver biopsy or laparoscopy depending on what's causing your liver problem
Sometimes, other blood tests to check for the problem causing your jaundice
With a liver biopsy, the doctor will put a needle in your right side to take out a sample of your liver to look at under a microscope. With laparoscopy, the doctor will make a small cut in your belly and put a thin viewing tube through the cut to look at your organs.

How do doctors treat jaundice?
Doctors will treat the underlying problem.
Itching usually slowly disappears as the liver improves. If itching is severe, your doctor can prescribe a medicine that may help.
If the cause is a blocked bile duct, a flexible viewing tube (endoscope) may be used to open it. Source: Stanford Nursery. Link: https://med.stanford.edu/newborns/professional-education/jaundice-and-phototherapy/faqs-about-phototherapy.html. Field: Hepatology . Disease: Jaundice </s>
