Nadolol, Serum/Plasma
Use
This test measures the concentration of Nadolol in serum or plasma. It is typically used to monitor blood levels of Nadolol in patients who are prescribed this medication for hypertension or angina. Ensuring that drug levels remain within the therapeutic range helps in optimizing dosage regimens and improving patient outcomes by preventing potential adverse effects or underdosage.
Special Instructions
Submit only one specimen per order and ensure that specimens are not shared between multiple orders. Blood should be drawn either in a plain, red-top tube for serum or in a lavender-top (EDTA) or pink-top tube for plasma. Ensure that the serum gel tube is not used as it is unacceptable for this test.
Limitations
The test requires careful adherence to specimen collection and handling instructions to avoid any pre-analytical errors. Failure to use the specified collection tubes or improper storage can lead to specimen rejection or inaccurate results. Moreover, the test will not detect nadolol levels if they are below the assay's reporting limit. The test results should be interpreted in conjunction with the clinical picture and other diagnostic procedures.
