Gallbladder
To confirm the suspected diagnosis, and to rule out other possibilities, imaging tests are ordered.
The definitive diagnosis of an MPS is made using a biochemical test that measures the specific enzyme (known to be reduced or absent) in the individual's tissues or bodily fluids. Genetic testing may also be used to confirm a suspected diagnosis
Blood tests, urine tests, and tissue tests can be used to confirm a diagnosis of lipidoses.
A blood test for Bartonella henselae may be ordered to confirm the doctor's diagnosis.
It is a biopsy.
Gaucher disease may be suspected based on symptoms and is confirmed with a blood test for levels of the enzyme. Samples of tissue from an affected area may also be used to confirm a diagnosis of the disease.
It is a biopsy.
A diagnosis may be listed as a known diagnosis, one that has been confirmed, or a possible diagnosis, one that is suspected or part of a differential list that tests will be done to either confirm or eliminate. This second type is called R/O (rule out), for example, a patient in the ER with chest pain may have the diagnosis R/O myocardial infarction (heart attack) until the tests have been completed to determine if the person did or did not have a heart attack.
The AFP test cannot be used by itself to confirm a diagnosis of liver cancer, because cirrhosis or chronic hepatitis can also produce high alpha-fetoprotein levels.
Biopsy
A biopsy can help diagnose Hodgkin's disease by obtaining a sample of tissue from the affected area (such as a lymph node) for microscopic examination. Characteristic changes in the cells, such as the presence of Reed-Sternberg cells, can confirm the diagnosis of Hodgkin's disease. The biopsy results can also provide information on the type and stage of the cancer, which is crucial for determining the most appropriate treatment plan.
