Fertility Questions

Are the ZRT labs as accurate as serum labs drawn in my doctor's office?

Yes! You will also receive additional information on hormones that you would not get from a standard serum test for infertility. For example, ZRT will test your stress hormone, cortisol, four times throughout the day to determine if your levels contribute to infertility. Low or high levels of cortisol can wreak havoc on the reproductive system and lead to infertility.

I don't know when I ovulate... what should I do?

In a normal menstrual cycle, you would ovulate around day fourteen, counting day one as the first day of your period. If you have a fairly regular cycle of about 28 days, complete the test on day twenty-one and we will determine if you ovulated and produced adequate hormones to sustain a pregnancy. If your cycle is consistent, but is shorter or longer than 28 days, estimate when you would begin your period and count backwards seven days. That would be equivalent to a collection on day twenty-one of your cycle. 

Can my doctor draw these labs in his/her office?

Yes, that is certainly an option. However, ZRT developed this test to avoid the inconvenience of going to the lab drawing station or doctor’s office on specific days and specific times, and accrue the costs of scheduling a doctor visit and taking time off work. The ZRT blood collections are done early in the morning in the convenience and stress-free environment of your home, and are dependent on the timing of your cycle, which may not coincide with your doctors’ availability.

If I don't get a regular period, when should I test?

If you get your period irregularly, then wait until you have a period, and twenty one days after you begin bleeding, collect your first sample. Then if you have your period on day twenty eight, collect on day three. If not, collect on day 38 (ten days after your first collection).

I'm nervous to prick my finger - will it hurt? 

The lancets we use give a quick and nearly painless finger prick. However, if nervousness is an issue, ask someone such as your healthcare provider or a friend to help you. Once you've completed one finger prick, the next will seem simple.

What does a good bloodspot look like?

A good bloodspot is no more than one drop per circle. It forms like a raindrop from your finger which can be lightly dropped onto the paper. Be careful not to touch your finger to the paper, but let the blood naturally. When the blood drop is adequate size, it should form a circle that fills almost the entire ring. Make sure not to overlap spots or put two drops of blood on top of each other.

How can I make the bloodspot easier to collect?

Increasing your blood circulation will help greatly – just warming up your hands helps, but swinging your arms around or doing jumping jacks will get your blood flowing. It is also important to have the blood spot card immobilized in a place that is easy to reach once you have started the blood flow. Tape the card to the edge of a low table so your arm and hand hang downwards. Once you’ve pricked your finger with the lancet, place the hand over the card and begin collecting. If bleeding slows, very gently “milk” your finger from the top to the finger tip. Don’t squeeze the finger hard, as this will stop blood flow. 

Will my doctor understand my lab results if they are bloodspot?

Yes. The ranges of bloodspot hormones are essentially identical to serum, so the hormone levels should be familiar to your doctor.

Can ZRT treat me if my levels are abnormal?

No, ZRT does not sell therapeutic products or provide treatment recommendations. However, we are happy to consult with your healthcare provider with regard to what treatment might be best for you.

My labs were very abnormal - what should I do?

If you don’t currently see a healthcare professional that specializes in fertility, use the “Find A Provider” function on our website to find a healthcare provider in your area. You may also want to talk to your OBGYN who can help you find a fertility specialist should one be needed.

Can men complete this test? 

Yes, and while we don’t recommend this test for issues related to male infertility, cortisol, thyroid, vitamin D3, testosterone and estradiol levels can all indicate infertility problems in men. 

Why don't you test for AntiMullerian Hormone?

AMH is a very good test that is popular for assessing ovarian egg reserves.  ZRT is looking into this test, but has not developed it yet. Elevated LH and FSH on day three of the menstrual cycle will give similar information as these tests indirectly indicate low egg reserve. 

Why does ZRT offer a fertility profile?

ZRT has worked with many healthcare providers who want to help women with fertility issues, but don’t know what tests to offer. We are using the same testing methods we have used for nearly fifteen years and have combined them in a convenient test that will help you find answers specifically related to infertility. 

Has your testing worked for other women?

ZRT has worked with thousands of healthcare providers over the past fifteen years, and has provided tests for thousands of women that helped them find their reasons for infertility. We have many stories of women who now are moms because ZRT testing gave them answers to what their hormone problems were and helped guide their treatment.
