You will have to pee into a cup, because the lab assistants must examine your urine. This fluid is somehow the waste which is filtered out of your body by your kidneys. The lab assistants will look for stuff which should not be in the urine, for example bacteria or white blood cells.

Some very strange words are connected with urine and Langerhans Cell Histiocytosis. These words are:


Polydipsia is the medical word for beeing horribly thirsty and drinking an awful lot of fluids (up to 7 litres per day). This can happen when some hormones in the body get mixed up by a disease like Langerhans Cell Histiocytosis.


Polyuria is the medical word for urinating (peeing) an awful lot and not being able to change this by drinking less. Like Polydipsia, Polyuria can appear when a disease like Langerhans Cell Histiocytosis disturbs the hormone production of your body.

Diabetes insipidus

Diabetes insipidus is the medical word for a disease which can cause polydipsia and/or polyuria. Diabetes insipidus occurs due to a problem with the endocrine system. Many small organs called endocrine glands build the endocrine system all over your body. They secrete hormones. These important substances tell your body what and when to do, for example how much to pee. Special doctors called endocrinologists know how to treat patients with hormone problems like diabetes insipidus.

Water Deprivation Test

The water deprivation test is a special examination which can help the doctors to discover diabetes insipidus. If they suspect you have hormone problems, you will perform this test. You will have to stop drinking for a while, so your doctor can see if you pee less. Although you will probably hate being thirsty, this is very important to choose the correct treatment.
