Estronex

What is the minimum specimen requirement for this test?*

The minimum requirement is 13 mL of urine.

How long do I have once the specimen is collected to get it to the laboratory? (Please see proper specimen storage under the "Shipping" section)**

The specimen should be received within 4 weeks and must be collected in the tube that arrived with the kit as it contains a preservative.

I am collecting for the Estronex test and I usually get up several times during the night to use the restroom. The directions say to collect only the first morning urine. When should I collect my first morning urine?

It is best to collect the first urine when you are getting up for the day. If you usually go to bed at 10 pm and then wake up for the first time at 4 am, and then again at 6 am, collect both the 4 am and the 6 am urine together. If you get up every hour during the night or drink water during the night, collect the first urine for the day.

Can men do the Estronex test and if so, what might be the differences in the results?

Men are able to do the Estronex test; however, the normal range is thought to be outside of the reference ranges for women. Men should consult their clinicians regarding this test.
