A couple of posts have recommended assessing the fat cotent of 
breastmilk by this process.

Can I ask for more details?

Do we have research to show what the desired  range of fat content is 
in breastmilk?

Does it take into account the fact that fat content of breastmilk 
changes  *all the time* according to the volume of milk in the breast?

Does it take into account the knowledge we now have that overall, 
milk gets fattier as the baby gets older?

Does it distinguish between different types of fat?

And  what do you do with the results,  if they show the baby doesn't 
have enough/has too much fat (if there is a robust enough baseline 
for comparison)?

I can see the commercial value of doing a creamatocrit in the dairy 
industry - in farming, cows are milked in the same way at the same 
times each day and you might then get a consistent result. You might 
want to breed different cows to make different milk, or you might 
need to test a sample of milk mixed from many different cows to check 
you are selling a product that meets with current regulations.

But human milk from human mothers? The creamatocrit is interesting 
for use in research, perhaps, but I just don't understand its 
application as a clinical tool

Nevertheless,  I am more than happy to have my scepticism  removed :)
