Question 1

if a blood test showed your kidneys were healthy why would a kidney ultrasound come back abnormal?

Accepted Answer

Blockage: Kidney ultrasounds evaluate blood flow into the kidney and urine flow out of the kidney.  Often, kidney function can be preserved long after blood flow or urine output begins to deteriorate.  Also ultrasounds can pick up cysts and tumors that blood tests don't.

Question 2

blood test egfr (fasting for 12 hours) came back as 86 today, but kidney ultrasound and urine test 2 months ago were totally normal. is there any reason to be concerned about this egfr level? could it be due to dehydration?

Accepted Answer

See below: 86 is not meaningfully different from 90. You may wish to get tested in 6 months or so.
Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
Get HPV and Covid vaccines. Wish you good health!

Question 3

30 yr old female. had renal ultrasound for micro hematuria. left ureter jet wasn't firing. kidney blood test normal. could this be cancer?

Accepted Answer

Blood in urine: It is not likely that you have a cancer.  I see you are taking anticoagulant meds.  This can predispose to hematuria.  Given the ultrasound finging of what could be slowed urine passage thru one ureter, coupled to microhematuria, I recommend further dialogue with your docs.  An IVP or better, a CT-IVP is a valuable next test.

Question 4

i was sent to get a blood test because of kidney stones that a sonogram revealed i have. my results show that my mpv  is high at 12.7 is that normal?

Accepted Answer

Platelets: MPV=mean platelet volume
This is a little used value in thehemograom, with only weak correlation with disease states. Like red cells, younger platelets tend to be bigger, and stress reactions may prompt earlier release from the marrow. Many possible causes, but little utility in isolation.

Question 5

my 13 year old daughter got her results of her blood test and the doctor said it was abnormal and i ask what came abnormal and he said her kidneys?

Accepted Answer

Abnormal Labs: I would love to help.  However, without more specific information it is irresponsible of me to comment.  That said i would be happy to help if you can get the results or provide some history and symptoms.

Question 6

hi kidney profile blood test. result is below reference range. sodium 134 mmol/l range is 136 - 145. what does this mean please. thanks?

Accepted Answer

Almost normal: 134 may be normal for you. Normal tests are the central 95% of the distribution in health people. In other words, 5% of normal people have some abnormal lab values.

Question 7

what do i need to look for on my blood test to tell me how my kidneys are?

Accepted Answer

: A simple chemistry blood test, chem 7 or SMA7 or renal panel, can tell you the kidney function. However, people may have kidney problem but kidney function is still normal by blood test. To completely rule out any kidney problems, a renal panel + a formal urinalysis + kidney ultrasound are required. Give example: people born with one kidney still have normal kidney function and normal urinalysis.

Question 8

what blood tests test kidney function? what kind of blood test do i need to show how well my kidneys are working?

Accepted Answer

BUN and creatinine: Blood urea nitrogen (BUN) and a serum creatinine are used to measure how effectively your kidneys are screening out those waste products from  your blood.  They are a routine test almost universally done with blood chemistries.

Question 9

i have just had a blood test and it came back saying my kidneys and liver are on borderline what can this mean please help?

Accepted Answer

Not enough info: Provide the specific test results and you can get a specific answer.

Question 10

i have rhabdomyolysis. with every blood test, my kidneys are okay. as my cpk went down from 126,000 to 721, should i worry of my kidneys still???

Accepted Answer

If your kidneys are: ok at this point it is unlikely they will have a problem as your CPK reduces. Discuss your concerns with your health care provider who knows all the specifics of your case and renal function.
