Gallbladder
To confirm the suspected diagnosis, and to rule out other possibilities, imaging tests are ordered.
The sample of biopsied tissue is examined under a microscope. Giant cells called Reed-Sternberg cells must be present to confirm a diagnosis of Hodgkin's disease.
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.
Xeno=stranger Diagnosis= to identify cause or nature. So, xenodiagnosis the process of identifying a disease using a strange organism (usually a clean, sterile vector). The vector bites the patient, and if the patient has the suspected disease, the parasite (as it almost invariably is) grows in the body of the vector. The doctor then examines this growth to confirm the diagnosis.
It is a biopsy.
Blood tests, including complement fixation (CF) tests and hemagglutination tests, also help to confirm the 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.
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.
