Great Smokies Lab offers a test for intestinal permeability/malabsorption and it tells you (a) if you have leaky gut and (b) if you have malabsorption (you can have both simultaneously). DirectLabs marks up the cost... I paid only $65 through my ND for this test (I don't recommend it for unpotty trained diaper-wearers as it involves urine collection over a 6-hour period). This appears to be a pretty standard test to determine the degree of intestinal permeability and seems to be the gold standard of tests - quite a number of studies in the scientific realm use this particular test.
Metametrix offers a test for dysbiosis which would seem to suggest leaky gut (if you're leaky, then you probably have dysbiosis, no?). This test looks at the gut microorganisms that are present in urine - presumably if you have a leaky gut, your gut critters will be floating willy nilly into your body where they don't typically reside.
most of the (western) science of intestinal permeability (IP) has to do with the effect of drugs on IP though some studies consider IP in relation to surgery or liver disorders. not surprisingly, not many (western) studies examine dysbiosis (or dysbacteriosis) - most of that research is from the USSR/Russia (does anybody here read Russian?!)/Eastern Europe. a good free article or three to read:

as for why one has leaky gut... well, increased intestinal permeability is often linked with physical trauma from burns, surgery, hemorraghic shock and other physical trauma. i'm wondering when docs will consider labor to be physical trauma and look at how many mamas (and babes) have increased intestinal permeability after birth.
