One of the measures of kidney function is the glomerular filtration rate (GFR). Other tests that can assess the function of the kidneys include assessment of electrolyte levels such as potassium and phosphate, assessment of acid-base status by the measurement of bicarbonate levels from a vein, and assessment of the full blood count for anaemia.
Hyperkalemia is an elevated level of potassium (K +) in the blood. [1] Normal potassium levels are between 3.5 and 5.0 ... When kidney function becomes compromised ...
The kidney has many functions, which a well-functioning kidney realizes by filtering blood in a process known as glomerular filtration. A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney.
Serum creatinine (a blood measurement) is an important indicator of kidney function, because it is an easily measured byproduct of muscle metabolism that is excreted unchanged by the kidneys. Creatinine itself is produced [ 5 ] via a biological system involving creatine , phosphocreatine (also known as creatine phosphate), and adenosine ...
Glomerular hyperfiltration is a situation where the filtration elements in the kidneys called glomeruli produce excessive amounts of pro-urine. It can be part of a number of medical conditions particularly diabetic nephropathy (kidney damage associated with diabetes).
An elevated creatinine level is considered abnormal and may indicate decreased kidney function. [ 31 ] Blood urea nitrogen (BUN) - Also measured using a BMP or CMP , blood urea nitrogen is an indicator of how much nitrogen is in the blood at the time of the phlebotomy.
High blood pressure (hypertension) Type 2 diabetes. High cholesterol. Sleep apnea. ... or diarrhea — conditions that can lead to dehydration and negatively impact kidney function. ...
A simple means of estimating renal function is to measure pH, blood urea nitrogen, creatinine, and basic electrolytes (including sodium, potassium, chloride, and bicarbonate). As the kidney is the most important organ in controlling these values, any derangement in these values could suggest renal impairment.
