Laboratory Tests

We use standard blood, urine and faeces tests that are available through collecting agencies in New Zealand and we use other tests that require us to send samples overseas.

The standard New Zealand tests are administered via DHBs who allocate funding to some tests and not others.  

The values the laboratory uses as normal are taken from a statistical analysis of the test results of the people being tested. Thus if your test results show that you are in the range this dies not necessarily mean that you are healthy.There is an optimal place to be within the range and we take this into account.

The testing of adrenal and sex hormones is quite complicated and there are issues with all of the methods. Testing the blood and the saliva gives us the level of the hormone we are testing at one moment in time and in that one place. It does not tell us how much of the hormone is inside the cell, not how much we are able to use. The urine can be measured to give a longer timeframe (eg 24 hours)  and the metabolites (breakdown products) of the hormones in the urine can be measured to give an idea of how much has been used. For this purpose we favour the type of urine testing done by an American laboratory called Precision Analytical. Their website offers good explanations about the reasons for their style of testing:  www.precisionhormones.com

For cost reasons we most often work with what is available locally in the first instance.

Functional Tests:

  • A metabolic profile tells us how well the chemical reactions in your body are progressing ( or not)
  • A liver detoxification profile tells us if one one of the pathways in your liver is under performine and needs extra support
  • A digestive stool analysis can tell us if you require supplementation with enzymes or probiotics for example

Comprehensive Genetic Testing

It is now possible to look at your genetic profile to see which areas of your biochemistry and physiology are more vulnerable and require more care. Some people think they would not want to know this because it is foretelling their misfortune with respect to their future health. Actually, the genes are only a map; whether you follow it or not is directed by your environment and your nutritional choices. You can steer yourself away from this by prior knowledge. Your nutrition decides which of your genes are activated and which are turned off. Did you know that your heart attack potential as an adult is contributed to by the nutrition of your father before you were conceived. We are responsible not only for our own health but also that of our children - even as a man. 

Cholesterol

The standard cholesterol tests are not sufficiently detailed to give us enough information about our risk. We think of the LDL as bad and the HDL as good but within both of these there can be dense or light cholesterol. We can send blood to Germany for breakdawn of the subfractions of cholesterol. The level of oxidised LDL can also be measured. It is when LDL becomes oxidised that it causes a problem and plaques develop in the walls of arteries. Knowing your level of oxidised LDL is an important tool for the prevention of heart attacks and strokes and for making decisions about whether to take medication and/or nutrients.
