The diagnosis step is to test  blood and a sample of  stool. Blood tests can show whether anaemia is present or not. Also there are two specialised blood tests known as the erythrocyte sedimentation rate (ESR) test and the C reactive protein (CRP) test. These tests look for tell-tell changes in the blood that point to the presence of disease and inflammation. stools will be checked for infection. X-rays may also be taken to help assess the extent of the condition.Sigmoidoscopy. The diagnosis will then need to be confirmed by directly examining the level and extent of the inflammation of the bowel. This is initially done by using a sigmoidoscope - a flexible tube containing a camera that is inserted into your rectum.
The procedure is not painful, though  may be given a sedative to relax. The procedure typically takes around 15 minutes.  The sigmoidoscope is only capable of looking at the rectum and lower part of the colon. If it thought that  ulcerative colitis has affected more of  colon than that, another examination
will be required. This is known as a colonoscopy. A colonoscopy uses a longer and more flexible tube called the colonscope, which allows entire colon to be examined.Before having the examination it will be necessary for  colon to be entirely empty. Therefore the patient will be required to take some strong laxatives before the examination. Again, the procedure is not painful though patient may feel some initial discomfort.
patient will be given sedatives to help  relax. The procedure takes around half-a-hour.
