What Causes Difference In Kidney Function Test Results?

Hi, may I answer your health queries right now ? Please type your query here...

Dear Sir/Madam



Name: Deepak Gupta

Age: 32, MALE

Weight : 75 Kg. Height 175 CM.



Question: I was diagnosed with anxiety/Hypertension four years back ( at age

28). All the routine blood test, KFT, Soography of abdomen Lipid profile, Blood

sugar parameters were OK. I m taking blood pressure medicine ( Stamlo 2.5 mg/

Niavas 2.5 mg). My blood pressure remain in control all the time. Rarely it goes

above 140/95.



Every year i used to do routine check up. 2 days back i went for routine check

up. All parametrs were OK.





My Kidney Function Parameters show below reading



Sr. Blood Urea = 36 mg/dl (one year back it was 18 mg/dl)*

Sr. Creatinine = 1.01 mg/dl (one Year back it was 0.94 mg/dl)*

Potasium = 4.62 (one year it was 4.5)

Sodium = 143.5 (one year it was 142.1)

CBC = all figures normal

ECG = Normal



I showed these figure to my phyiscian. He stated that every thing is normal. But

still i was confused and immediately went to different pathology and done KFT

again.



Sr. Blood Urea = 19.24 mg/dl

Sr. Creatinine = 0.91 mg/dl



Dear Support i need your help, how these reading changed within 2 hours. are

these parameters abnormal. Please Help me. I have no physical symtomps and feel

OK. I have no family history of hypertension and Diabetes and any heart or

kidney problem not maternal and parental side.



Waiting for valuable reply



Thanks and Regards

Deepak Gupta

Hi!
welcome to HCM!
Your results are absolutely normal so no need to worry!
If these tests are run in 2 different labs from the same sample then also there is a chance of 10 per cent variation in results which is acceptable internationally but if test is done after 2 hrs then blood urea and creatinine may vary within normal reference range.So nothing to worry.Take care!
