"Normal blood counts are difficult to state as they vary with the age and sex of the patient 

as well as where they live. Higher values are usually seen in people who live at higher elevations. 

The reference ranges for each test will be printed on the laboratory report form and will be specific to your locale."  However, it is to some degree subjective, given the mobility of our society.

More blood info

Ask your doctor to have the lab do a CBC  (complete blood counts) 

that gives the basic info (first 5 above) plus type of white blood cells....

It will give an indication of whether you may have been affected 

by the oil or by the chemicals .... or both.... or neither.... 

but borderline might not mean OK.  

Machines do most of these tests now a-days, 

so especially ask the lab technician to comment on how the red blood cells look.

These people need MORE HELP!

Ask the lab technician to also check the reticulocyte count.

Please request the information for doctors and their patients who've worked with oil or chemicals containing 2-butoxyethanol  (oil spill cleanup, painting business, etc) and something doesn't look right with your blood.
