Creatinine is a waste product that forms in your muscles from a natural process called metabolism. It is filtered out of your blood by the kidneys and then excreted in urine. Doctors measure
creatinine levels to check how well your kidneys are working.
Full definition
For instance, the UK Idexx laboratory considers the top - normal blood
creatinine level in cats to be 177 umol / l, which is about 2.0 mg / dl in the American system.
After a physical exam, most order a combination of these tests: a complete blood count (CBC), biochemical panel, urinalysis, protein - to -
creatinine ratio in the urine and bacterial urine culture.
Elevated levels of
creatinine in the blood — which indicates how well the kidneys are filtering waste — and high protein levels in urine — a condition called proteinuria — can alert clinicians that an individual is suffering from chronic kidney disease.
There is a 4 stage classification system based on the level
of creatinine as a benchmark for the severity of chronic kidney disease.
Pets with
blood creatinine levels of up to about 4 mg / dl have also survived happily for many years with appropriate treatment.
Genetic testing might help determine if a donor kidney carries greater risk for renal complications after transplantation, such as a higher
serum creatinine concentration or earlier allograft failure.
The best monitoring test in those situations is a 24 hours
creatinine clearance test or another test that estimates the pet's GFR.
Some claim that albumin's presence in elevated amounts in either test will pick up an impending kidney problem earlier than an abnormal blood
creatinine test.
The claim that regular creatine monohydrate needs to be buffered in order to prevent it from breaking down
into creatinine with the body is inaccurate.
A newly discovered factor may prove key to solving this riddle: The researchers showed for the first time that brown fat activity is affected by a variable known
as creatinine clearance, which is related to renal function.
In a few cases, dehydration, heart and blood pressure medications, stomach antacids, antibiotics, non-kidney disease and arthritis medications can be responsible for minor blood
creatinine increases in dogs and cats.
Many active people taking creatine don't know this though and are alarmed by
high creatinine levels popping up on a blood test.
Other common bloodwork changes occurring with hypothyroidism include a mild anemia (low red blood cells), mildly low sodium level, high cholesterol, and a mildly
elevated creatinine level (due to decreased blood flow to the kidneys caused by a slower metabolic rate).
When a patient tested positive for AKI — determined by serum
creatinine values — the provider and a pharmacist received an alert in the form of a text page informing them of the diagnosis and encouraging them to take appropriate steps.
When creatinine levels are elevated in the blood of a kidney transplant recipient, it is an indication that the transplanted kidney is not functioning well.
Regular creatine is broken down into a waste product
called creatinine before the active compound is absorbed - this lowers the absorption rate.
If creatinine levels are too high, this ratio can indicate reduced kidney function.
The latter was achieved without any significant (P > 0.05) influence upon the urinary excretion of iron (20.7 ± 9.5 to 21.7 ± 13.8 nmol /
mmol creatinine).
(3) You must also provide the MRO numerical values
for creatinine and specific gravity for the negative - dilute test result, without a request from the MRO.
The researchers detected more than 61,000 diagnoses of AKI, as defined by
rising creatinine level.
Your insurer may run tests which are part of a routine metabolic panel
including creatinine blood test and a BUN (blood urea nitrogen) test.
While these are not diagnostic for hyperthyroidism, certain things such as an elevated red blood cell percentage, an abnormally
low creatinine level, and an elevated ALT can all point towards hyperthyroidism.
If the source is thought to be the kidneys, a follow - up test called a urine
protein creatinine ratio is performed.
Vets typically look
at creatinine, BUN, and urine specific gravity tests, among others, for indication of kidney disease.
Depending on how the test is performed, high blood glucose, vitamin C supplements and certain antibiotics (cephalsporins) can falsely
raise creatinine readings.
This keeps the BUN and
creatinine from increasing dramatically because they are the byproducts of protein metabolism.
Unfortunately, the
initial creatinine tests can lead to misdiagnosis and inappropriate treatment.»
Regression models were adjusted for age, sex, race / ethnicity, education, income, smoking, BMI, waist circumference, and
urinary creatinine concentration.
It was instantaneously converted into the worthless
byproduct creatinine which does our muscle cells no good!
The results of the study are unsettling: After just one week of drinking all cold beverages from polycarbonate bottles, BPA concentrations in the participants» urine increased by an astounding 69 percent, from 1.3 μg / L
creatinine before using the bottles, to 2.1 μg / L after using the polycarbonate bottles for a week.
If the BUN and
creatinine do not drop significantly after 24 - 48 hours of intravenous fluids then the prognosis for recovery is poor.
However, the only large study comparing it with monohydrate showed no difference in performance or muscle creatine content, and it found pretty similar increases in
creatinine between the two.
Working together, the two realized that Shih's optical probes, which have been used for applications ranging from non-invasive glucose monitoring to sensing environmental hazards such as oil spills, could also be used to
determine creatinine levels in patients with kidney disease.
It has been shown to be ineffective because over time it will turn to
creatinine which, although the name sounds similar to creatine, doesn't work.
As time progresses, however, it seems that creatine users» bodies learn how to eliminate
creatinine more efficiently from the blood.
It also found that conversion rate to
creatinine slows as the pH of the creatine itself is raised above 7.
Naturally, the more dilute the specimen is, the less protein will be in it and measuring the urine
creatinine content adjusts for that.
For the continuous variables, rate of atrophy was significantly associated with baseline log tHcy (partial r = 0.41, P < 0.001) and with
plasma creatinine (partial r = 0.22, P = 0.049).
Given the fact that creatine is unstable in aqueous solution and will eventually degrade into
worthless creatinine, I find it very disturbing that companies would actually sell liquid creatine.
Some studies on vegetarian diets have shown increased risk of protein deficiency, iron deficiency, decreased
muscle creatinine, and elevated blood levels of homocysteine.
