Overview

There is no single diagnostic study of choice for the diagnosis of Fanconi syndrome, but it can be diagnosed based on clinical presentation and laboratory tests.

Diagnostic Study of Choice

Study of choice

  • There is no single diagnostic study of choice for the diagnosis of Fanconi syndrome, but it can be diagnosed based on clinical presentation and laboratory tests[1][2].
  • Labratory findings are more fundamental than anything else to confirm the diagnosis. The laboratory tests usually are performed when[3][4]:
Diagnostic results

The following results of Laboratory tests are confirmatory of Fanconi syndrome[5][6][7][1]:

Sequence of Diagnostic Studies

The laboratory tests usually are performed when:

Diagnostic Criteria

The diagnosis of Fanconi syndrome is basically made by labratory findings and the clinical presentation of the patients only lead physicians to investigate the lab tests. The definition of Fanconi syndrome has been quite confusingly in the literature as a definite diagnostic criteria has not been established[8][2].

The following results of the laboratory tests together are confirmatory of Fanconi syndrome[7][6][5][1]; however, also in cases of one or more absence of these findings, the disease might have been called Fanconi syndrome in some literature and some interpreted then that they should not have[8].

because of various pathophysiology of disease in patients, the definition of exact concentration limits of these ingredients is not practical and their deviation from the normal range is considered diagnostic.
