Metanephrine Urine ELISA Kit

  • Created on the 4 March, 2017.


Metanephrine urine ELISA kit is designed for measuring in vitro quantitative levels of metanephrine (metaadrenaline) in human urine samples. This assay has a minimum detection level of 13.0 ng/ml.


Metanephrine (metaadrenaline) are classified as catecholamines hormone molecules and they can be produced as a metabolite of adrenaline (epinephrine). These hormones are vital in the regulation of blood flow and pressure throughout the body during periods of physical and emotional stress. These metanephrine hormones are useful in detecting tumors such as pheochromocytomas and paragangliomas, since these tumors are found to be producing these hormones in excess. Assays that are currently being used to measure the presence of catecholamine-secreting tumors (pheochromocytomas or paragangliomas) include urine catecholamines, plasma catecholamines, urine metanephrines and plasma free metanephrines. All of these procedures have varying specificity and sensitivity.

Urine metanephrine assays are used to measure the total amount of metanephrines that is released into the urine in a 24 hour period. Due to the fact that the concentrations of this hormone may fluctuate significantly throughout the day, the urine test may be able to detect excess production that could have been missed using the blood test. The current guidelines recommends using either/or both urinary fractionated metanephrines and plasma free metanephrines for initial biochemical testing. Metanephrine urine ELISA kit can be used for a number of different diagnostic applications.


The minimum sensitivity limit of metanephrine (metaadrenaline) using current human metanephrine urine ELISA kit was approximately 13.0 ng/ml. The dynamic range for this assay is 20.0 – 2,-000 pg/ml.

Your secretory IgA ELISA kit gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA kits. You have such an easy and simple system, yet it is very effective.
