The last time I got a request for fat droplets in urine I got quite excited
as the urine looked like chyluria.
The patient was concerned about his health and presented the urine to the
GP. After planning my analytical approach, I opened the pot, and was
welcomed with a distinctive aroma. Several folk in the lab recognised the
smell as Cerumol ear drops (Arachis oil (peanut oil), paradichlorobezene,
chlorobutanol and oil of turpentine) and when challenged by the GP, the
patient admitted using Cerumol for his ears but denied putting it anywhere
else. He did however make a miraculous recovery after the discussion with
the GP and his urine has been clear since.

Concidentally with a query about urine myoglobin appearing on the mailbase,
here is another one about an occasionally requested urine test.
Now and then we get a request for 'fat droplets in urine'. The reason for
the request is usually suspicion of a post-traumatic fat embolism. The
method we use is to mix some urine with Oil Red O and look for red blobs
under the microscope. As I remember the method was developed 'in house'
quite a number of years ago with advice from our Histology department.
We would welcome the views of colleagues as to whether this represents the
'state of the art', whether we could do better, or whether we are wasting
our time (apart from reminding biochemistry staff what a microscope is used
for!).
All I could find on PubMed were a few case reports and only a single entry
in the mailbase archives.
Thanks in anticipation
