by classical cytogenetic analyses. The RT-PCR and FISH procedures are the most sensitive methods to
detect these fusion transcripts.(3)
Useful For: Supporting a diagnosis of synovial sarcoma
Interpretation: A positive result is consistent with a diagnosis of synovial sarcoma. Sarcomas other
than synovial sarcoma, and carcinomas, melanomas, and lymphomas are negative for the fusion
products. A negative result does not rule out a diagnosis of synovial sarcoma.
Reference Values:
Negative

Synthetic Glucocorticoid Screen, Serum
Clinical Information: Synthetic glucocorticoids are widely used and have important clinical utility
both as anti-inflammatory and immunosuppressive agents. The medical use of these agents, as well as
their surreptitious use, can sometimes lead to a confusing clinical presentation. Patients exposed to these
steroids may present with clinical features of Cushing syndrome, but with suppressed cortisol levels and
evidence of hypothalamus-pituitary-adrenal axis suppression.
Useful For: Confirming the presence of listed synthetic glucocorticoids (see Interpretation)
Confirming the cause of secondary adrenal insufficiency This assay does not detect fluticasone
propionate.
Interpretation: This test screens for and quantitates, if present, the following synthetic
glucocorticoids: betamethasone, budesonide, dexamethasone, fludrocortisone, flunisolide,
fluorometholone, megestrol acetate, methylprednisolone, prednisolone, prednisone, triamcinolone, and
triamcinolone acetonide. The presence of synthetic glucocorticoids in serum indicates current or recent
use of these compounds. Since several of these compounds exceed the potency of endogenous cortisol
by 1 or more orders of magnitude, even trace levels may be associated with Cushingoid features.
Reference Values:
Negative
Cutoff concentrations
Betamethasone: 0.10 mcg/dL
Budesonide: 0.10 mcg/dL
Dexamethasone: 0.10 mcg/dL
Fludrocortisone: 0.10 mcg/dL
