Question 6

i've got a glucose blood test tomorrow morning and have to fast 10 hours before and was wondering whether you can drink water?

Yes: Water is fine; nobody wants you to be dehydrated just for some blood tests, but they don't want you to take any food or other fluids which may elevate your blood sugar.

Question 7

i did blood test and creatine kinase was very high, i think more than 1000. i am going to the gym 4,5 days a week. should i drink more water or?

Accepted Answer

Normal: Strenuous muscular exercise elevates the CK - this is NOT abnormal. Drinking water is certainly a healthy thing to do when you're sweating, but it will not have any effect on your CK.  Don't worry about it. (A CK of  10,000 would be significant)

Question 8

my ck/cpk creatine kinase blood test came 315 about 3 months ago redid the test yesterday and came 256. does this mean not drinking enough water?

Accepted Answer

Ck/CPK: Creatintine kinase is one of the enzymes in your muscle. If you are male and you have reasonable muscle mass this could be your normal serum level.

Question 9

had a blood test taken that said i have an abnormal red blood cell count of 5.49. i live in a high altitude area and dont drink much water.is this count a problem and if so what thing can one do to lower rbc? is this sign of concern?

Accepted Answer

: Yes, dehydration and living at high altitude can both contribute to an elevated red blood cell count or polycythemia.Trying to hydrate better is what you can try for now as serial counts will be needed in order to identify a pattern and in case further workup is needed. Your doc remains your best reference and can coordinate going forward.

Question 10

hello- what is the normal accepted absolute lymphocytes range for a 33 year old male? every site and lab has a different number. thanks. 
also, would drinking a bottle of water right before the blood test dilute my blood a lot and affect the results?

Accepted Answer

It's variable: Lab-to-lab variability is because of differences in equipment and techniques.  Doctor's are trained to make good decisions despite these challenges in comparing results, and from my own experience I can attest that it is not a problem.
