This was awesome, very clear explanation for what I was looking for "how do we measure GFR," better than wikipedia and khan academy in this specific case
Thank you for enumerating the limitations in testing.
A very nice comparison between people with different age, sex or ethnicity as regarding eGFR. It really helps me alot. Many thanks
I literally learned more in this 10 minute video than in the past !
May i ask if the patient has normal creatinine and the ultrasound shows has 60% renal disease and 40% normal. What is that mean. How stage is that? Thank you for the reply.
very good explanation for determining age-stages for egfr.
A very informative lecture.
Thank you so much
The Best informative video, thanks..
Great lecture. Than you.
What other labs good for kidney health assessment? TY for this clearly explained on creatinine and BUN and ratio. Tried Bun/creatinine ratio on my labs and 24, but am slender so will ignore as eGFR is 85-90.
Sodium, potassium, PTH and phosphorus are labs that can give you an idea. If the kidneys are not working well but there is not advance kidney disease the body will compensate, the labs would look good. Symptoms of CKD are feeling tired, puffy eyes and lower back pain, however most of the times people ignore or do not have any symptoms.
@@fanmar8723 a friend said her puffy eyes from thyroid (hypo). Rarely see phosphorus listed on labs now days. Do wonder what minerals loosing when need to get up at night. TY Read a few yrs ago a CC? (3 letters) lab was best for condition of kidneys but forget name of lab.
For country India what will be the eGFR for Male, Age 37 and creatine 1.1? Please let me know.
And what is the normal range of egfr for India??
May I ask? If the patient has a normal level of creatinine but when he/she undergo ultrasound for kidney and the result is not good, what does this mean?
It could many things. For example. If one kidney is damaged, the other one will compensate. And therefore no change in the Creatinine level.
Thanks
What are the numbers of kidney function and creatinine ?
thank you!
Kudos for the Video clip! Sorry for the intrusion, I would appreciate your thoughts. Have you thought about - Trentvorty Perfection Kidney Theorem (just google it)? It is a great one of a kind guide for improving kidney function without the headache. Ive heard some decent things about it and my work buddy after a lifetime of fighting got excellent results with it.

Creatinine result 222 what is this?
Hallo! my creatinine serum was normal but my urine creatinine clearance was below normal. I dont get the logic with it and what is its impact on my kidney? im experiencing a foamy urine since December 2020.
I think u should contact a doctor for this issue because it varies from person to person so consulting a doctor is the best as for the foamy urine I think it's the increase in protein which the kidney can't filter so u should consult a doctor for sure . I hope it helps ☺️
Are you diabetic?
How are you doing? Foamy urine is not good.
@@mohammadalbahri4633 im not...my sugar level is normal
Does 122 ml is bad at age 23?
You haven't mentioned about cystatin c
Seems like using levels of creatinine to determine GFR is as about as useful as using BMI to determine if a person is overweight. Both can give an inaccurate result if you're at all active and muscular.
Iam a lean 300 pound bodybuilder and my creatine is 1.9 and my egfr is 20. it is normonaly 1.4 and egfr 57. It went up after I train heavy weight for 30 days.
@@danjones7046 the best test for kidney function you can get if you're an active individual, especially a weight lifter, is the Cystatin C test. I asked my Dr. to do this test when my eGFR levels came back low and my creatinine levels slightly elevated. The Cystatin C test came back normal at .75 (normal range is .62-1.15mg/L).
@@goldenera4ever I did just email my doctor. Shold I stop training and eating protein? Thanks you
@@danjones7046 well, first of all, I have to say I'm not a qualified expert on what you should do. All I can say is I stopped the preworkout supplement I use, but I didn't stop lifting or drinking protein shakes. I normally don't take in more than a 100 grams of protein a day anyway. Too much is hard on the kidneys so ask your Dr. what to do.
@@danjones7046 BTW when I said in my previous comment that I stopped the pre workout I meant a couple weeks before my blood work. After the physical I started using it again.
I’ve been sent to a kidney specialist because my eGFR on paper was a 79. All my other blood work is normal including kidney numbers (high normal) but I am a weight lifter and I am 20-25 pounds heavier than someone my age / height on average. Plugging my weight and height into the eGFR calculator it goes to 91 instead of the 79 I was given. The average calculator still gives me 79 without that
You need to test cystatine C...it is more accurate than creatinine serum for who does weight lifting or bodybuilder..
epic video bro nice job
“Bro”
Hi I’m 22 and my GFR came back at 59 does that mean I’m at stage 3 of Kidney disease ?
You definitely need to have that checked soon.
Really?
I am aged 72.male.weight 69kg.In may 2022 my eGFRwas 60 ml/min/1.73m2.creatinine 106 or 1.2 mg/dl.Urea6.7 mmol/l.40mg/dl.frequent urination yellowish colour.
In March 2022, eGFR is 53ml/min/1.73m2 creatinine 118 umol/L-1.3mg/dl
urea 8.3mmol/L or 50mg/dl
still urinate frequent yellowish colour.
Please help understand whether there is a danger of any renal failure? Thank you.
should see doctor, i am 104 at 18
A multivitamin will definitely turn your urine bright yellow.
I'm worried - I have continually higher Creatinine levels, around 120 and eGFR of 57 - my doctor is not overly concerned!! For the past 3 years, my eGFR levels have been 60.4, 63.8 and recently 57.2. My Creatinine levels have stayed pretty consistent at 120 - 140. Now, I weight train and have a fair amount of muscle mass (according to other people, I don't think I have), so could my eGFR levels be underestimated because of my higher Creatinine levels? All my other levels are within range. I do eat about 200g protein per day, 1g for 1lb of bodyweight. Surely, if I had Kidney damage my numbers from 2018, till now would have steadily decreased over time? I know I need a better way of testing that leaves out elevated levels of Creatinine.
How are you holding up? Just curious cause similarly my my gfr always read 60 now it's at 90 but my creatinine is 0.9 standard goes up to 1.2
@@nicksardo3105 Hey Nick, hope you're feeling well. It's good your GRF has gone up. I had my last test, it went from 57 to 61, I still asked to see a specialist.
When I saw the specalists, he basically laughed and said "You are very muscular, you have nothing to worry about, forget the numbers!". I was like, wtf - all I want is an accurate test, so I can adjust my lifestyle if my readings/Kidneys are not working great. Reduce protein, not workout so hard etc.. So I have a phone call setup, in a few weeks, with some from his department who may be able to do a test that by-asses the Creatinine.
Its been a hard slog though - it gives me the hump, soon as people see that I'm fairly muscular (nothing big in anyway), they automatically assume its anxiety and there is nothing to worry about. o.0
@@megmucklebones7538 oh that's good your post worried me It sounded as if you were going to be on insulin soon lol jk. Glad it worked out & I'm sure you're fine was just curious because I'm a bit of a hypochondriac myself despite being a good shape.
It sounds similar to me .
@@nicksardo3105
What did you do?
Thanks
Why are Blacks measured differently. Not all black ppl have big bodies.. this gives a false sense of how well the kidneys are working
Iam a lean 300 pound bodybuilder and my creatine was 1.9 and my egfr was 20. any comments?
Man, your probably at CKD. Go visit your doctor cause it seems bad result
@Moby I found out what caused me egfr to be 20 percent. It was a pain med calld sodium diflunicate otherwise called vlotaren but in tablet form. I wemt off that crappy med and my creatine and egfr went back to normal.
I went off the med and took
My husband have creatien level 1.3 and the GFR range 47 please give reason
last Year 103
Go visit your doctor
Very Succinct 👁️🙏👁️
In the UV/P formula, maybe we can give the patient a substance that can temporarily block the organic secretary pathway in order to obtain a very accurate GFR.
You have my exact thoughts 😊
I have 78% and I'm African American. Is this normal?
blacks have more creatine
Creatinine 57 mg/dL >=20 what's this mean
I have a question for any doctors out here. I am a 30 year old male athlete (6'1 235lbs). My blood test results said my creatinine was on the high side (1.23), the normal range said .67 to 1.17, however, I read that normal for adult males is up to 1.30. Also my GFR read >60 is this healthy? About an hour before the test, I drank a pre-workout and worked out for an hour. I know your supposed to fast before a test, but the test was done randomly at my Dr. Visit. Can doing these things cause an inaccurate result? Other thsn creatinine serum levels everything else is in the normal range. I live a healthy lifestyle, gym 6 days per week, pretty healthy diet in addition to taking daily vitamins (fish oil, vitamin d, vitamin b complex, milk thistle and a lot of water. Also, 2 days prior to the test, I had a horrible stomach bug and threw up a lot and hard. Should I be worried with these results?
If you are 30 and have a gfr under 60,that is concerning. I am going through the process for live kidney donation,if your gfr is under 60,at any age you would not be able to donate your kidney. My age is 65,just got recent gfr results, it was 71.Ideally over 90,they would love.But 61-89 is intermediate level and they will weigh all factors moving forward, like age.Good luck,and good health.
@@larrymosher5045 Hi, thank you for the reply. I had spoken to my Doctor and I read the results wrong. My GFR read greater than 60. For that test a normal result is = or>60. In other words, mine was well above. Your response is greatly appreciated regardless.
What does 167 eGFR mean?
Impossible ., max gfr is 120
@@saikumaroriyan8263 not impossible went to the doctor less than a month ago and mine was 135 😐. I’m looking all over the internet to find answers but I’m still as confused. Is it too high?
@@cozygamer344 may be u have calculated through formula ., if u undergo DTPA scan u will get real estimates
Just reading through all the comments here below, seems everybody has understood what has been said here except me ,..... But then I have a low IQ. I would love this explained in laymen's terms.
I unfortunately have CDK and this is the best treatment I've seen so far with herbs from Dr emuakhe from Africa.I plan to use it in the future when friends/family ask about it..
Far from perfect
Indian❤
why does race play a role in GFR?
Because gfr is related to creatinine, which is related to muscle mass. So darker skin people have more muscle mass.
@@dwho432
I see plenty of African Americans who are very obese.
I'm really can't put too much credibility in eGFR. It's the little "e" that's concerning ...
Race factor isn't used anymore
@@sharpie6888 Correct. It has been removed because it prejudiced black people against transplant listing because they were treated as having less severe renal dysfunction than they actually did. Black kidney donors were also harmed because they were donating kidneys when they had undiagnosed kidney disease due to the racial correction factor.
Yes, it does
