Doctor Chung,

I have some questions re: to my latest blood test and urine test.


Reference ranges were listed on the blood test form for all items
except for these three items. Please check the PDR or other
reference books and list the standand reference ranges for these
three items:

This was NOT a 24 hour urine test--it was a spot test of urine.
urine sodium
urine potassium
urine chloride

Please comment on these results:
serum sodium 140 (135-145)
serum potassium 3.7 (3.5-5.1)
serum chloride 103 (98-107)

This was NOT a 24 hour urine electrolyte test--It was a spot test of
urine. urine sodium 20
urine potassium 25.3
urine chloride 26

TSH 7.56 high (0.27-4.2)

Differential
Eosinophils 6.5 high (0-4)

I found this quote in a book:

"Urine sodium concentration is useful in determining the cause of
hyponatremia. Urine sodium <20 mEq/L reflects sodium conservation by
the kidneys and is found in ECFV depletion and edematous states CHF,
nephrotic syndrome and cirrhosis."

I would appreciate your comments,
Jason



Published average reference ranges are useless in interpreting most
lab tests because there are inter lab variations of materials,
methods, and other circumstances. That is why they have reference
ranges printed with the results.

Further, lab tests cannot be interpreted in the absence of an exam and
a clinical history. For example, aspirin can affect TSH results and a
definitive interpretation would require T3 and T4 results as well.

Last, since the normal range is usually defined as + or - 2 standard
deviations from the normal population mean, 95.4% of the normal
population is classified as having a value in the normal range. This
means that 2.3% of the normal population will test slightly high and
an equal number will test slightly low. If you have a lab panel with
a pile of tests, you become likely to be slightly out of range on a
test or two even if you are normal.

The disclaimers having been presented, you can get a wealth of general
information on lab test results at

Charly,
Thanks--I'll visit the site. My doctor ignores items on blood tests and
urine tests that are within the reference ranges. That is the major reason
that I wanted the reference ranges for urine sodium, urine potassium and
urine chloride. If you have that info. in one of your reference books,
please post that information. I was not able to find that info. in any
website. I hope that the website that you mentioned above has that
information.
Thanks again,
jason
