Why Urine instead of Blood or Saliva?

Do I have to have a prescription to order a hormone test?
Yes. We must receive a request for testing from a partner physician in order to process your labs. To find a physician near you, visit our Provider Directory.

How are samples returned to the laboratory for testing?
Shipping samples back to the lab is simple and easy. Place your frozen samples and frozen ice-pack back into the original packaging and send it back inside the pre-addressed shipping bag provided in your kit and drop the package into any FedEx drop-box prior to the last pick-up of the day.

Will you bill my insurance carrier?
Physicians Lab will file an out-of-network insurance claim for you with your insurance company and upon request, will preauthorize your insurance to give accurate pricing when your physician orders lab testing. For billing question or to have your insurance pre-authorized, please call 877-316-8686

What forms of payment do you accept?
Physicians Lab accepts all major credit cards (except Discover), debit Cards, Flexible Spending Accounts and Health Saving Accounts.

Can I still take supplements, hormones or medications when testing?
Patients should continue to take their medications regularly. However, certain supplements should be avoided and your hormone therapy schedule may need to be altered for sample collection. Please refer to the instructions enclosed in your testing kit for details on which medications and supplements should be continued or altered.

I collected my sample three weeks ago, but never mailed it – is it still good?
As long as the urine has been stored frozen, it is still ok to send urine in. The hormones in urine are quite stable frozen (and even at room temperature) and the results should not be affected by long-term storage in a freezer. However, recollection may be advised If there have been changes in your menstrual cycles, hormone medications, and other treatment plans that could affect your hormones since the collection date.

In what order do I collect my samples?
Please view our collection instructions. Most people collect the first sample as soon as they wake up (waking collection) and every 4 hours after waking. While it is important to collect in very consistent 4-hour intervals, the time period that you start collecting is less important. You can start at collecting at any part of the day as long as you collect every 4-hours AND your waking sample is collected immediately after waking.
For example; if you wake up at 7am and forget to collect the waking sample, you can collect the “4-hours after waking” sample at 11am, then collect at 3pm, 7pm, 11pm, and collect the “waking” collection when you wake up the following day.

I ate or drank before collecting my samples – are they still valid to send in?

We do not have any fasting requirements so you may eat before or after your collections. However, your fluid intake should be limited to 16oz between each collection and you should limit fluids that can dilute your samples, such as caffeinated drinks or teas.

If your fluid intake was not limited to 16oz or if you ingested fluids that might dilute your sample, there is a chance you may have to collect your samples again. In the event that the sample collection is deemed unacceptable, Physicians Lab will send you another kit (in which you may incur a shipping and handling charge).

What do I do after I collect my samples?
Promptly log your sample collection date and time under “Log Collection Times” on your Patient Dashboard, on your kit instructions, or in through our text messaging and email instructions. Freeze your samples until you are able to return them to us. When you are ready to return them (as soon as possible), place your completed forms and tubes back into the box we provided and into the pre-labeled FedEx envelope for return shipment and drop the package into any FedEx drop-box prior to the last pick-up of the day.

I did not keep my urine sample cold following collection. Can I still send it in?
Yes, although urine should be refrigerated to reduce bacterial growth, the hormones are quite stable at room temperature. We only ask patients to freeze the samples to prevent the samples from getting very hot during transit in warmer months (and in warmer climates).

If I am sick, should I wait until I am well to collect my samples?
It is not recommended to collect testing when you are sick, however, most illnesses and medications will not adversely affect the results. Certain anti-inflammatory medications can impact your Cortisol results (which may lead to a recollection) and some medications that are taken vaginally or applied to the genitals could alter the results so we suggest you wait until you are feeling better and not on any of these medications to collect your samples.

If I am on antibiotics, should I still collect?
Antibiotics do not alter hormone testing, however, we often suggest that patients wait to perform hormone testing until they are feeling better whenever possible.

Can I collect samples at any time during my menstrual cycle?
If you are still cycling, there are a few tests that must be collected during a specified window of time during your cycle. The OPTIMAL time of collection is 7-days before your expected period, however, there is a 3-day window so women who still experience periods can collect 6,7 or 8 days before the expected period. Menopausal women and men may collect at any time during the month. You may also use the mobile web tools and have the best date chosen for you based on your last period.

I am unable to login because I forgot my username and/or password.
If you have forgotten your password, you can use the “Forgot Password” link to receive an email with instruction on resetting your password. Three (3) unsuccessful logins to the Patient Dashboard will lock your computer out of the system for 24 hours. If this happens, please call Physicians Lab for assistance at 1-877-316-8686.

Can I do testing if I am pregnant or nursing?
Although testing can be performed during pregnancy and/or nursing, hormones and vitamin levels are greatly affected during these stages. Please consult with your physician to make sure he/she is aware that you are pregnant/nursing before testing.

Can I drink alcoholic beverages?
No, alcohol is a diuretic and will make it more difficult to hold your urine.

Can I exercise while collecting?
Yes, but keep in mind you are on a fluid restriction. You shouldn’t over exert yourself while collecting.
