Question: Hi I recently had a life line screening and one of the blood test was for my kidneys. My creatinine level was 0.66 lab range (0.76-1.27). I fasted for 18 hours before the test and only drank water. I take lisinopril and hydrochlorothiazide for blood pressure. Should I be worried about liver problems or something else or is it not that low? I hade a few blood test last year and the levels were .87and .78. I don’t know the ranges for those but they were normal.

Brief Answer:

It is just normal and you need not to worry about it

Detailed Answer:

Hi,

Based on the history and reports you have shared, these are just normal ranges and it's rise is of more concern. In your case it's just about normal and there seems nothing at all to be worried about related to your kidneys.

This test is not for the liver as there is a separate set of test for liver issues and if you have had any history related to that you may need to have liver function tests were done which include ALT, AST, and bilirubin etc.

Low creatinine can be a normal variant with low protein intake or low body mass index of low protein content but with such values, it also doesn't seem to be the case.

Hope I have answered your query. Let me know if I can assist you further.

Brief Answer:

Low protien intake or low muscle mass can cause low creatinine

Detailed Answer:

Hi,

Your levels are just about normal and there isn't anything to be worried about. Very low creatinine levels can sometimes be due to low protein intake or low muscle mass individuals.

Fasting can lower the intake and may slow down metabolism and low creatinine but sometimes dehydration can worsen it too so nothing is exactly predictable regarding fasting.

Liver functions you have not shared yet so I don't find any reason to call it abnormal or severe lover issue as there isn't anything yet to support that.

Keep good hydration and repeat liver and kidney function test after a week.

Hope I have answered your query. Let me know if I can assist you further.

Thanks for getting back to me. The last liver test I had was about a year ago and my alt was a little elevated. The dr said it wasn’t worrisome. Everything else was good

Brief Answer:

You need to have an ultrasound liver and viral serologies if remains high

Detailed Answer:

Hi,

Such mildly high ALT can be due to fatty liver which is a common condition nowadays and should be ruled out on Ultrasound abdomen so that fat free diet and other lifestyle modifications should be commenced however viral serologies like hepatitis B and C should also be done to rule out any such possibility only if repeated ultrasound also have high ALT.

Hope I have answered your query.

Take care
