What’s New @TestoChecker®

Scroll down for NEW TESTS


The following is a brief description of two significant changes we have implemented. More detail can also be found by scrolling down this page. The big change affects the way DHEAs, Progesterone, the Estrogens and Testosterone [the androgens] are collected and tested, and this ultimately benefits our clients. The other change relates to the postal service. Read on..


Multi-Point Saliva Collection Method


In short – We  are increasing the number of samples collected, to get a better picture.        

How – Where we once relied on a single saliva sample to test these hormones, i.e. Testosterone, the Estrogens, [precursor] DHEAs and Progesterone, we will now utilize several samples, spread over two hours.

We call this the Multi Point Saliva Collection Method [MSM]. More about this, including ‘Advantages to MSM’, further down.


Please note: Tests which only include Cortisol or Melatonin, or both, have not changed. This is because these hormones already benefited from MSM. It is the Androgen Hormones, i.e.Testosterone, the Estrogens, DHEAs and Progesterone tests which are impacted by this change.


From Australia Post to [900] Collection Bases


To ensure the integrity of your samples, they must be delivered, within 36 hours of being collected, to a specimen collection center.  There are 900 collection centers in handy places around the country (except QLD, but we’re working on it). We’ll show you exactly where to find the one nearest to you.

Whilst it’s still too early to confirm, efforts are underway to open more collection centres, with a focus on Brisbane.  Sign up to our ‘QLD residents update’ list to stay informed, these can be found on the test kit description pages.


Advantages Of MSM for Salivary Hormone Analysis


| – Most androgen hormones are pulsating, meaning they are produced in bursts or fluctuating patterns. With the sample collection now spread over 2 hours, the laboratory can get a ‘broad-spectrum view’ of this pattern, providing a more valid final result for interpretation.


|| – Multi-Point saliva collection substantially reduces the odds of error occurring due to interfering agents, external factors or natural fluctuation in hormone productivity.

                         Why Won’t We Use The Postal Service?


During 2019 we sadly witnessed a decline in standards at Australia Post resulting in frustration for many. Unfortunately, and after much consideration, we lost faith in our ability to meet our commitment to our clients which includes the safe and timely transport of their saliva samples.


How Many Saliva Samples are Tested?


Androgens: The number of samples required for our NEW tests can vary, but is usually five. These five samples are to be collected into separate tubes over a two hour period, i.e. one sample every 30 minutes, preferably commencing in the early morning, 30 minutes after waking. All five samples are used to test your hormone levels, creating a final, more credible result.


Tests which include Cortisol and Melatonin involve various numbers of saliva collections (from 2-4) depending on the individual test. To see more go to the specific test description.


New test kits


We are pleased to present the following four new test configurations. These are the result of diligent research and also consultation with experts in endocrinology as well as Functional Pathology. All tests now employ MSM.

Good laboratories, such as the one we have used since commencing operations, are continually looking for improvements based on current research. Changes to methods or protocols are not made overnight and are the result of diligent research, peer review and data analysis. This considered change has been made in line with the overall objective of the testing laboratory: The pursuit of excellence.



Short Note from the General Manager



“Whilst the luxury of using the postal service will be missed by a few, these changes mostly represent a tightening of standards which translates to increased accuracy, and at the same cost. This can only be seen as a win.”

Looking forward to a healthy future !
