Brief Answer:
normal range of kidney function 0.8 to 1.2

Detailed Answer:

Hi,

Creatinine is constantly produced from muscles of a person and its blood level does not change with fasting state or after meal. normally it should be between 0.8 to 1.2 mg/dl but in a very muscular person even a slightly higher level may be normal. in a thin built person you can have 0.6 also.

kidney function tests generally include

Blood- urea, creatinine, uric acid, sodium potassium, calcium, phosphorus, eGFR estimation

urine- urine routine, urine spot protein creatinine ratio.

Radiological- ultrasound

isotope studies - DTPA scan.

a creatinine level ranging between 1.1 to 1.38 is only slightly at the higher limit.

there is nothing to worry- you have to be in regular check up of your nephrologist.

i think you should get an Ultrasound KUB with post void residue, urine routine and urine spot P/C ratio and a complete KFT and discuss with your doctor.

meanwhile- avoid pain killers, avoid nonveg food, take less salt in diet, keep a check on BP. keep it below 140/90 with the help of medicines.

Does the below tests suffice for initial screening and based on the reports can i go for other tests and along with these if I do microalbumin/creatinie ratio this will also help for initial screening.

o     BUN/Creatinine Ratio
o     Creatinine
o     Uric Acid
o     Calcium
o     Blood Urea Nitrogen

Brief Answer:
yes

Detailed Answer:

hi,

Yes these will suffice,

but no need of BUN/creatinine ratio
and instead of microalbumin /creatinine ratio-- go for spot urine protein/creatinine ratio as i have mentioned earlier.
Also an ultrasound KUB should be part of first screening for kidney disease.

Does the creatine range change with the method of doing like some labs use modified jaffe kinetic which shows the range 0.6-1.4 and jaffe kinetic which shows the range 0.9-1.3. The latest result test is done on XXXXXXX using modified jaffe and the value is 1.38.So as per this also is there any problem and in the urine test also there are no albumin/glucose present. But one nephrologist suggested doing ACR(albumin creatine ratio) which would clearly indicate if there was a damage so just asked about it.So is albumin and microalbumin same and protein and albumin one and the same


If I need to collect 24 hr urine sample should i collect entire urine or only 2-5 ml of urine sample every time for CCT?

Brief Answer:
normal is upto 1.2

Detailed Answer:
Hi,

albumin is a fraction of protein (it is one type of protein). normally in kidney diseases protein leaks in to urine . it can be albumin or any other protein. if we do only albumin testing we can miss some other protein which may be there in urine. so protein/creatinine ratio is a better option.

most labs now use modified jaffe kinetic method for testing, in any case any reading above 1.2 should be considered as abnormal and all efforts should be made to identify the problem. kidney disease can occur in normal range of creatinine also.

If I need to collect 24 hr urine sample should i collect entire urine or only 2-5 ml of urine sample every time for CCT?If creatine is increased can it be decreased with out using any medicines if it decreases what should be analysis?
doctor
Answered by Dr. Ravi Bansal 21 hours later
Brief Answer:
24 hrs means all urine

Detailed Answer:

Generally we don't collect a 24 hrs urine sample for protein creatinine ratio. we mostly do spot urine - that means a one time urine sample of around 10 ml.

but if you want to collect a 24 hrs sample. then you have to collect whatever you pass throughout the day whether it is 2 litre or 5 litre into the container. creatinine can be decreased by precautions as explained. if it decreases it means kidney is working better

Brief Answer:
1.2 is fine

Detailed Answer:
Hi,

Serum creatinine of 1.2 is fine and it shows a good kidney function for him. so now you have to keep a watch over urine protein excretion also- if that too is normal then we have a very good prognosis.

symptoms of prostate enlargement are urinary frequency, feeling of incomplete evacuation of urine at the end of urination, thin stream of urine and need of using more force and time to start urination.

Prostate enlarges in all men over time and the diagnosis can be confirmed by ultrasound and by uroflowmetry. If prostate is very large and causing obstruction to urine flow it can cause rise in serum creatinine. the symptoms can easily be treated with medications.

getting up at night for urination can be a presentation of prostate problem but it can also occur with infection , uncontrolled blood sugar and excessive intake of water at night.

Best wishes
