Examination of kidney function
Kidney Function Tests
Medical
tests play a very important role in the evaluation of renal function in
many diseases that affect the college, as the follow-up kidney patients
and predict ultimatum condition they have and these analyzes are:
(1) measuring the urea (Urea):
Urea
output is the President and the final metabolism of proteins in
mammals, consists of urea in the liver and then passes into the blood to
the kidneys, where he graduated with the urine.
And interference in the formation of urea from ammonia (NH3), which consists of toxic demolition of amino acids.

Although
the level of urea in the blood is an indicator of non-sensitive
function of renal However, the ease of measurement made of the tests
common and not the sensitivity of this test is that it must lose more
than 50% of the function glomeruli renal even affected the level of urea
in the blood, moreover, there are many reasons non-renal
origin can cause high urea in the blood, and the level of urea in the
blood is affected by proteins in the food and the amount of Rashih
glomerular kidney.

The
level of urea in the blood ranges from 20 to 40 mg / 100 ml blood (3.5 -
7 mmol / l) the level of urea in the blood Natroyjana Blood Urea
Nitrogen (BUN) ranged between 8-25 mg / 100 ml blood (0.9 - 8.9 mmol /
L) level of concentration of urea in the urine ranges from 20 to 40 mg /
100 ml blood, and in infants between 5-15 mg / 100 ml blood, and
children from 5 to 20 mg / 100 ml blood.
Reasons for the high level of urea in the blood:
Increase the level of urea in the blood in the following cases:

Inflammation of acute and chronic renal
Renal failure
Obstructive urinary
GI bleeding
Trauma and fall of the adrenal gland
Cases of dehydration, so as to have a large amount of fluid that occurs in such persistent vomiting and severe diarrhea
Mercury poisoning and certain other heavy metal salts

The reasons for the low level of urea in the blood:
Decreasing the level of urea in the blood in the following cases:

Liver
disease advanced, and in this case consists ammonia and fails the liver
to convert to Paulina Due to the severity of the disease, and multiply
risk in the presence of high concentrations of urea, because the ammonia
gas is extremely toxic, which is spreading in the whole body and the
impact Serious is on the brain as it leads to complete paralysis In
the case of the brain's cerebral palsy resulting from increasing the
proportion of ammonia enters the patient in a coma Hepatic Coma
intermittent, but with the increase in the proportion of ammonia in the
blood may lead to the patient in a coma long time may lead to death
Increase
the rate of dialysis Hemodialysis industrial and this affects the rate
of urea in the blood, where there are few to be up to less than normal.
Cachexia wasting diseases such as tuberculosis and malnutrition Malnutrition and famine Starvation

Causes an increase Tzakiz urea in the urine:
Increasing
concentration of urea in the urine when you eat a diet rich in protein,
and in cases associated with increased protein catabolism in the body
such as fever, untreated diabetes and hyper thyroid.
Concentration causes a decrease of the proportion of urea in the urine:
Less
than the proportion of urea in the urine when you eat a poor diet of
proteins, and in the building of proteins such as pregnancy and
lactation, and in cases of liver failure and kidney failure.

(2) measurement of creatinine Creatinine:
The
measurement of creatinine indicator of more honest for the safety of
the kidney function of measuring urea in the blood, a creatine anhydrous
Anhydrous Creatine as produced from phosphate creatine Phosphocreatine
after the loss of a phosphate group then passes blood to the kidneys to
come out with urine and appropriate concentration blood and urine
directly proportional to the size of the muscles of the body and not influenced by eating, and constant focus for the past 24 hours, so it is best to test the measure of kidney function.
The
level of creatinine in the blood varies between 0.5 - 1.5 mg per 100 ml
blood (60-123 micromol / l) concentration of creatinine in the urine of
about 1.5 g / 24 hours in males The concentration of creatinine in the
urine of about 1.0 g / 24 hours in females due to the different muscle size in both male and female
Increase the level of creatinine in the blood may result in:
-
Cases of acute renal failure and chronic - obstructive urinary
creatinine ratio, while at least 0.5 g / 100 ml blood does not mean any
diagnostic importance.
(3) creatinine clearance Creatinine Clearance Test:
This
analysis is more accurate than previous analyzes which reveals the
function of the kidneys in the past 24 hours, and also connects between
creatinine ratio in both blood and urine within 24 hours.
Rate
in males ranging between 90 to 140 ml / min while the female percentage
in the range between 80 to 125 ml / minute and reflect the rapid rate
of kidney glomerular Rashih
Is calculated Creatinine Clearance (c) as follows:
Uc × Tv
C =
24 × 60 × Sc
As

Uc
the level of creatinine in the urine creatinine level of Sc in urine
volume serum Tv complex at the 24 Hours 24 Hours is the number of hours
of the day 60 is the number of minutes per hour

Reduced creatinine clearance in all cases with low kidney function such as:
-
Drain water Water Depletion - pressure drop - tight renal artery (4)
measurement of uric acid (uric acid) (Uric Acid) Uric Acid
Is
the final product of the metabolism of purine Purine in humans, and
enters in the composition of purine nucleic acids include adenine and
guanine Adinine Guanine.
Change
the level of uric acid in the blood than an hour to another, and one
day to another day, as many factors that affect the uric acid from the
long fast and the quality of food.
Acid
level Alorett acid in the blood ranges from 3 to 7 mg per 100 ml blood
in males (0.18 - 0.53 mmol / l) and in females ranges from the level of
uric acid between 2-6 mg ml blood (0.15 - 0.45 mmol / l).
Out
of uric acid by the kidneys as about 80% of the uric acid acid formed
in the body comes out with the urine, and the part Ketbaka come out with
yellow.
The amount of uric acid from acid in the urine emerging between 300 to 700 mg / 24 hours (1.2 to 6.3 mmol / 24 hours)
Half
of this amount comes from purine metabolism external (of eating) and
the other half of the purine procedure (body cells), so when you must
measure the amount of uric acid in the urine that the food is free of
purine before and during the 24 hours for the collection of urine.
Increase the level of uric acid in the blood in the following cases:
-
Gout Gout - cases of eclampsia and pre-Pre - Eclampsia & Eclampsia -
blood cancer Leukaemia - drug treatment of cancer Damm - renal failure -
the first type of disease, glycogen storage Glycogen Storage Disease -
Type 1 - an overactive thyroid gland - in some alcoholics Alcoholism least the level of acid uric acid in the blood:
- Cases of acute hepatitis - to address drug and Allpurinol. Probenicid and cortisone. Increased
concentration of uric acid in the urine in cases of gout are the result
of metabolic disease in companion to any build up of uric acid, While
less concentration of uric acid in urine in kidney disease
