Got the results of a blood test. Low sodium and creatinine..I'm on lisinipril and hctz (hydrochlorothiazide). Could that have caused it? Also have pain under low-right ribs

Too much alcohol: The combination of lisinopril, HCTZ, (hydrochlorothiazide) and 3 alcohol drinks a day can cause low sodium. That's too much alcohol - sorry. The pain under your right ribs may be originating in your liver or gall-bladder as both live there. That should be checked. Low creatinine (even below the lab reference) is not harmful and reflects your muscle mass and normal kidney function. (I presume you're pretty small). ...Read more

You are normal: Creatinine levels are a reflection of muscle mass and kidney function. Bad kidney function never results in low creatinine. If you are skinny and do not eat much meat, your creatinine may be lower than "normal" but it is not abnormal at all. There is no need to try to increase your creatinine. ...Read more

Stop worrying: Reference ranges are set so that a few percent of healthies fall outside. Low urea and liver enzymes are never wirrusome if you feel well. If you Are a man with low creatinine, it may just be your muscles asking for more resistance training. Best wishes ...Read more

My creatinine is 0.41 (low) and my sodium is also low in my blood work. I have suffered of frequent urination 10 to 20 a day. Are my kidney bad?

My creatinine is 0.41 (low) and my sodium is also low in my blood work. I have suffered of frequent urination 10 to 20 a day. Are my kidney bad?

Urinary frequency: I would want to know whether your very frequent urinations are in small amounts or large amounts each time and what your total 24 hour fluid intake and total urinary volume is. If you're taking in over 2 quarts of fluids and putting out almost as much urine daily,you may be diluting your serum sodium and your kidney function is not the problem. If you have low urinary output you have small bladder ...Read more

Hi, my son 6 years old, when healthy, had bloods done, results were low ferritin, low lymphocytes 1.8, low wbcs 4.6 and low serum creatinine.

Not to worry: All of these things, with the exception of the low ferritin, are fine. The low creatinine means his kidneys work uber-great!. The WBC likely reflects mild suppression from a recent viral illness. The low ferritin is very common, indicating he needs more iron in his diet or a supplement. Please do not get in the habit of focusing on lab numbers when your child is healthy. He is healthy - enjoy! ...Read more

5yr girl with 7 past urine tests in row show trace blood in it, no u.T.I.! so checked serum creatinine an it's ok but cbc, iron on low side, .Any clue?

? urine Ca/cr ratio: Sometimes this is a sampling issue, and a squat and pee sample is often a vaginal wash out with all sorts of things in it.If it is a good clean catch specimine i would wonder where the blood is coming from.Small amounts can accompany excess calcium loss through the kidney tubules.A spot check of the urine ca/cr can pick this up, usually some protein in the pee along with it.Talk with your doc. ...Read more

I keep waking up with swollen hands no heart or kidney problems. Last blood work everything was fine the only thin low was my creatinine serum?

Swollen hands: Sorry but you need to be more precise as we need more info. When was your last blood work relative to swollen hands? If blood before these symptoms started, need repeat labs. Otherwise, time to consider autoimmune conditions. Or recent travel/camping. Ill contacts. New medications (perhaps b/c methylprednisolone), herbs, dietary supplements etc regardless of how natural pure & organic. Go c ur doc. ...Read more

Blood test: estimated creatinine clearance test (low), what could it indicate? EGFR & creatinine normal. Potassium & sodium low. 28yr/f

How do you FEEL?: Many (maybe most) pathologists and nephrologists aren't impressed with the current practice of labs estimate GFR, creatinine clearance and so forth from a spot creatinine. Some formulas include race "because black people are more muscular than white people" -- these were never intended to be applied to individuals. Frankly, if your others labs are healthy, I'd ignore it. ...Read more
