The new tests that launched in April 2022 by Mayo Clinic Laboratories:

ASYN | Alpha Synuclein Immunostain, Technical Component Only

This test is useful for the identification of alpha synuclein in neurogenerative disorders.

CITR | Citrate Excretion, 24 Hour, Urine

This test is intended for diagnosing risk factors for patients with calcium kidney stones and monitoring results of therapy in patients with calcium stones or renal tubular acidosis.

CITRA | Citrate Excretion, Random, Urine

This test is useful for diagnosing risk factors for patients with calcium kidney stones using random urine specimens and monitoring results of therapy in patients with calcium stones or renal tubular acidosis.

FCSC | Synthetic Cannabinoid Metabolites Screen, Expanded, Urine

This test is a cannabinoid screen via urine specimen by way of high performance liquid chromatography/tandem mass spectrometry.

FRDIG | Digoxin, Free, Serum

This test is intended for evaluating recrudescent (breakthrough) digoxin toxicity in renal-failure patients and assessing the need for antidigoxin Fab to be administered.

Additionally, this test is useful for deciding when to reintroduce digoxin therapy and monitoring patients with possible digoxin-like immunoreactive factors (DLIFs).

KRASW | KRAS Somatic Mutation Analysis, Peritoneal Fluid

This test is intended for detecting molecular markers associated with response or resistance to specific cancer.

NFLC | Neurofilament Light Chain, Plasma

This test is useful for assessing neuronal damage related to various neurodegenerative diseases.

NSE | Neuron-Specific Enolase, Serum

This test is useful as a follow-up marker in patients with neuron-specific enolase-secreting tumors of any type, as well as an auxiliary test in the diagnosis of small cell carcinoma and the diagnosis of carcinoids, islet cell tumors, and neuroblastomas.

This test is useful as an auxiliary tool in the assessment of comatose patients.

NSESF | Neuron-Specific Enolase (NSE), Spinal Fluid

This test is useful as an auxiliary test in the diagnosis of Creutzfeldt-Jakob disease, as well as in the diagnosis of small cell lunch carcinoma metastasis to central nervous system or leptomeninges.

VITB3 | Vitamin B3 and Metabolites, Plasma

This test is useful for assisting in the diagnosis of suspected vitamin B3 deficiency or toxicity and may be useful in determining response to therapy.
