 From what I've read, triglyceride levels seem to equate, to a first  
approximation, to total fat.

The simplest explanation would appear to be that the mum pumped off a  
little milk while full. (That's the easiest time to pump, after all!)  
Hartmann's findings have shown that "41-95% of the variance of the  
fat content of milk was explained by degree of breast emptying."

  A second sample taken after thorough drainage might tell a  
completely different story.
