I just received a diurnal cortisol test. Seven saliva samples are to be collected throughout the day, the first one upon waking and the last one at bedtime.
According to the instructions, no meat for 12 hours before the first sample, no dairy, eggs, or caffeine, no cruciferous vegetables and only vegetarian food for the whole day.
Could all those foods possible affect the test results in some way...? It feels there isn't much left to eat or drink at all...!
Crikey! Whose test is that? Do they give a reason to avoid them?
I do the Regenerus test and they say no food or drink on the day that contain caffeine. They say to avoid eating one hour prior to each saliva collection but there is no restriction on which foods you can eat. The only restriction is if testing melatonin and then it says to avoid nuts, fruit, fruit juice, wine, rice and coffee.
Interesting,when I did my saliva test in Synlab -German lab in Croatia,they never advised about not eating certain foods prior to testing, just about teeth brushing and smoking,which I dont,does this mean that my cortizol results are not valid.
I have no idea, my reply to thecat68 details what Regenerus say which is vastly different from what her lab says.
I discovered that there were only three containers in the box ( when I am supposed to send them seven samples) and they replied they had sent me the sex hormone test kit by mistake...so the instructions could apply to that one rather than cortisol...?
It could well do. Presumably they are sending you the correct kit, it will be interesting to see what those instructions say.
Yes, it’s on its way!
It's by a German lab called Verisana (available on Amazon). No explanation given.
