Low Gfr Blood Test
Should i be worried that i consistently test in low 80s on GFR blood test? Is there anything I should do?
Can GFR be low if i has not had a drink of for about 14 hrs before the blood test? Result=85.1ml/min/1.73 m2 thx
GFR and dehydration: You can have a low GFR due to dehydration and the figure of 85 ml/min is an estimated gfr. You did not mention your bun, sodium, chloride or creatinine and that would have been helpful in determining if you were really dehydrated. Ask your doctor to order a 24-hour urine for creatinine clearance and protein and that will tell you exactly what your GFR is, actually not estimated. ...Read more
Blood test: low alk phos & vit d, c-react protein 7.35, na 146, creat up from 60 to 80 & crcl down frm 101 to 76 in 2 mo, anion gap high, GFR 60 why?
More than one issue: The lab values you provided suggest more than one issue, one being kidney disease and the other being inflammation and may be more. Lab tests need to interpreted in the clinical context and you should discuss these results with your doctor at your earliest to prevent further damage. ...Read more
Ignore it: The "gfr" given on lab sheets these days is a subscientific estimate of the rate at which water passes from blood into the filtrate that will become urine. For a healthy person, the "gfr estimate" is not helpful. It ignores variability in body musculature, how much protein you have eaten recently, and other factors. ...Read more
I had a blood test done & results: AKI warning grade 1. Creatinine 107 umol/L. Estimated GFR 55 'consistent with CKD stage 3A. What does this mean?
Kidney dysfunction: The kidney filters blood in order to draw out waste/urine. Your GFR (glomerular filtration rate) is a bit low, but not urgently low. Whether this is an acute (aki) or chronic (ckd) problem depends more upon you medical history and the original indication for obtaining this test. The physician who ordered it is better equipped to make an interpretation beyond this level. ...Read more
What is the meaning of the following blood test results creatinine from 1.67 down to 0.83. Ast(sgot) 50, bun creat ratio 22.00, est GFR less than 60?
Kidney and Liver T: Egfr (normal >60), creatinine, bun/cr ratio are all lab values to suggest how the kidney function is, ast is an enzyme secreted by the liver, if its elevated there is something wrong with the liver (it varies from mild to severe). Check with your doctor or mentor about the normal values and the abnormal ones. ...Read more
My blood test paperwork says GFR is 85.1ml/min/1.73 m2. Is this normal? The lab paperwork says chronic kidney disease?
Maybe: For the past decade there has been a fad to estimate GFR subscientifically from a spot blood creatinine, making every well-muscled man a "chronic kidney disease" case. The pathologists and nephrologists who have no use for cookbook medicine are unhappy about this. Talk with your physician about what's really happening. ...Read more
Blood test show creatinine @ 1.13/GFR 58L; was on norvasc/spironolactone/metoprolol 1yr w/no BP improve;cut spiro and meto;now take Norvasc (amlodipine) 5mg 2x day; BP117/74. Change of meds cause creat to rise?
Blood test RBC 4.07, Hemoglobin 129 Hematocrit 0.385 Monocytes 1.1 GFR 57 Alkaline Phosphatase 39 Also Urine Albumin/Creatinine 6.7?
Need more info: Trying to give you a "heads up" on the implications of these values is like knowing the full story of a book by just reading the table of contents. The best person to give you insight about what these lab values mean is the physician who ordered them and knows a lot about your general health and background. ...Read more
Blood test came back out of range-Glucose Random 4.4 Creatinine 56 Estimated GFR 103 Gamma GT <10 ALT 18 AST 15 I am 42 smoker dizzy tired what's wrong?
The numbers above appear normal, you cite the creatinine as 56 or is that 0.56 because the estimated GFR is ok.
Causes for fatigue/dizziness: smoking, diet, perimenopause, no exercise, thyroid, anemia, low B12, B6, low magnesium. For dizziness also consider sinusitis, allergies, otitis, low blood pressure when initially standing up, vertigo,less likely carotids, vascular,tumors, autoimmune ...Read more
I Have Thalassemia Trait and Blood Test Result Says i have Variant Hb .WBC 3.9 Range 4-11. MCV 73.2 R80-100. MCH 23.3pg R27-32. RDW 20.4 R 11-14.5 .Neutrophils 1.3 R 2.0- 7.5 Protein 80 g/L R 61-79 Creatinine 50 R53-97. GFR >90 is it Normal result?

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, you seem to have microcytic anemia, which may be due beta thalassemia trait and/or iron deficiency. Your neutrophil count is borderline low. It may be useful to consult a hematologist.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more
Amyloidosis, all my symptoms, heart, liver high ggt, brain, neurological, gasrto and urinary, lungs. GFR not released, what is the genetic blood test?
Self-diagnosis?: Amyloidosis can mimic anything. It's not especially treatable so there's no hurry diagnosing it. Ask about a serum protein electrophoresis and urine test for Bence-Jones for amyloid AL. Amyoid AF is a neuropathy / pain syndrome and I wouldn't waste the money. Amyloid AA labwork isn't specific; it's rare in the absence of leprosy etc. I'd have a fat biopsy -- maybe you actually do have it. ...Read more
Recently started perindopril for hbp. Blood test. Hameotology normal. B12/feratin normal creatin/gfr normal. Potassium 3.4 (ref 3.5-5.5). Problem?
Labs are all normal: Hi Lorraine, Perinopril is a commonly used, long acting med called an ACE inhibitor. (angiotensin-converting-enzyme) These medications can cause issues with *elevated* potassium or even kidney disfunction. Which is why your physician likely order these labs. Slightly low potassium is no reason for concern. Please add a few servings of K rich foods (spinach, potatoes, apricots) to your diet ...Read more
Afn amer GFR: "Afn amer glomerular filtration rate", stands for african american gfr. African-americans have more muscle mass than whites. Due to this, they have a different estimated GFR than whites with the same level of creatinine and the same age, sex and weight. See your nephrologist for more details. ...Read more
Their GFR.: Glomerular filtration rate is a test that tells how well the kidneys are doing their job. That is, how well/how fast they clear out fluid from the blood stream, which has impurities in it. African americans tend to have a different rate than the rest of the population, hence the designation in a blood test, since it is a more clear indication of how well their kidneys are doing. ...Read more
Means nothing: A high RDW is a measure of the variability in size among red cells. When it is low, it's a fluke of statistics, and you should ignore it -- lab "normals" are set so that a few healthy folks lie outside. I run a high RDW as a frequent blood donor, and elevation is a common first-hint that something may be unusual; many healthies have high rdw's for various reasons. Labs mean nothing in isolation. ...Read more

Possibly nothing: It depends on how low. Lymphs are one of the types of cells that fight infection but in isolated general questions like this without numbers it is very hard to answer and usually a slightly low lymph count is meaningless. In your case if concerned asked your provider that ordered your test. ...Read more
How low?: Labs mean nothing in isolation. If this is a search for a possible lupus flare, or a workup for rheumatologic disease, and the C3 level is quite low, it may actually be important. Reference ranges are set so that a few percent of healthies fall outside on either side. If the lab work was a screen and you're not far outside, don't worry. ...Read more
All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your "low" sodium may still be in the normal range. It may appear to be low if you drank a lot of water before the test, had excessive sweating recently. See this site for info.

You're healthy: I wish that labs would not even report the percentages of granulocytes. These fluctuate wildly with the minor stresses of life, and if the absolute counts of granulocytes and lymphocytes are fairly close to the reference ranges, you should simply not worry. ...Read more
Low-normal: We pathologists operate the clinical labs and are always telling folks, "treat the person, not the numbers." if you are otherwise healthy, I would draw no conclusion whatsoever from this number. In any case, you'd be more interested in the absolute values of Albumin (is it low?) and globulin (is it high?) these are at best pointers for the workup of unexplained symptoms / signs. Good luck. ...Read more
Can mean Vit K low.: If prothrombin time blood test is high, without other high levels, it can mean a vitamin k deficiency or warfarin use. Vitamin k helps in the function and viability of factors ii, vii, ix, and x and these affect prothrombin time. If there are other levels altered, it could be a factor v, or x deficiency, disseminated intravascular coagulation (dic), or liver failure. See your doctor to be sure. ...Read more
It is 8:
You have to discuss with the doctor who ordered the test as we can not comment on only one value in cbc. We need to know why the test was ordered, what your symptoms are and what the other values are. Lymphocytes of 8 are low.
Causes of low lymphocytes are either body not making not enough lymphocytes or they get destroyed. Common causes are
