Leeuwenhoek had stolen and peeped into the fantastic sub-visible world of little things, creatures that had lived, had bred, had battled, had died, completely hidden from and unknown to all men from the beginning of time. Beasts these were of a kind that ravaged and annihilated whole races of men ten million times larger than they were themselves. Beings these were, more terrible than fire-spitting dragons or hydra-headed monsters. They were silent assassins that murdered babies in warm cradles and kings in sheltered places. It was this invisible, insignificant, but implacable-and sometimes friendly- world Leeuwenhoek had looked into for the first time of all men of all countries. ~Microbe Hunters

Rouleaux Formation

For some reason, when someone says “rouleaux” I picture a hula-hoop. You know, in the Alvin and the ChipmunksChristmas Song, “I just want a hula-hoop”. It's irritating.
Well, it has absolutely nothing to do with that. Rouleaux formation is when blood cell pile on top of each other and you can see this under the microscope on a blood smear. The cells may look like: 
Doctors sometimes order a test called an ESR, or erythrocyte sedimentation rate, which shows how much your blood cells can settle by rouleaux in an hour of sitting in a thin vertical chamber. An increased sedimentation rate can non-specifically show multiple myeloma, inflammation, and even pregnancy. It is so non-specific, I don’t really understand the purpose or ordering the test anymore. Doctors are very particular when it comes to the way they want things tested. Just make sure, if you ever go to the doctors and he/she wants to test if you are pregnant and orders an ESR, that’s a litttttle unconventional. It is way too general to give any information away for itself. You should get tested for bHCG if you think you may be pregnant. As for multiple myeloma, I would want my doctor to be certain before telling me I have cancer.


Darn good and sure of it,
