The NSE Blood Test is used in the monitoring of patients with small cell lung cancer (SCLC).


Test Code: 140624

Also Known As:

Methodology: The ThermoFisher/BRAHMS KRYPTOR® assay employs Time-Resolved Amplified Cryptate Emission (TRACE) technology based on a non-radioactive energy transfer between a donor (europium cryptate) and an acceptor (XL665) in a sandwich immunofluorescent format using two mouse monoclonal antibodies.

Preparation: No special preparation required.

Test Results: 6-10 days. May take longer based on weather, holiday or lab delays.

Sample Report

Test Code: 34476

Also Known As:

Methodology: Enzyme immunoassay (EIA)

Preparation: No special preparation required.

Test Results: 3-7 days. May take longer based on weather, holiday or lab delays.

Description

The Neuron-specific Enolase Blood Test, or NSE Blood Test, is useful in the diagnosis and ongoing monitoring of patients with small cell lung carcinoma (SCLC). It may also be used in the diagnosis of other neuroendocrine tumors such as carcinoids, islet cell tumors and neuroblastomas. The test measures the level of neuron-specific enolase (NSE) in the blood serum.

The NSE Blood Test is most commonly used as a follow-up marker for patients with tumors that secrete NSE. Following successful treatment, NSE levels should fall. Consistent or rising levels, in the absence of another condition that could cause increased NSE levels, suggest a persistent tumor or tumor spread/recurrence. Other conditions that could cause elevated levels of NSE include epileptic seizure, encephalitis, brain injury, stroke, and rapidly progressive dementia.

The NSE Blood Test is not diagnostic. Results must be considered alongside clinical evaluation and other established diagnostic tests. Furthermore, NSE values can vary between manufacturers, so serial follow-up should be performed with the same test each time.

Fasting is not required prior to the test, and results will be available within two to three days. A doctor’s order and insurance are not required to order this test.
