A)
What to know about urine tests
for creatinine
B) What is serum creatinine? Serum creatinine (women): 53 -
115 µmol/L. Serum creatinine (men): 88 -
150 µmol/L. Urine creatinine (women) : 6 -
13 mmol/24 hours. Urine creatinine (men): 7 - 14 mmol/24 hours.
C)
Urine creatine = normally < 30 mcg Urine
creatinine (24-hour urine collection) values can range from
500 to 2000 mg/day (4,420 to 17,680 mmol/day).
Results depend on her age and amount of
lean body mass Normal results depend on your muscle mass and age. Ranges differ for men and women: Male: 0.8 to 1.8 g/day (7
to 16 mmol/day) Female: 0.6 to 1.6 g/day (5.3 to 14 mmol/day). Another
way of expressing the normal range for test results is: 14 to 26 mg per kg
of body mass per day for men (123.8 to 229.8 µmol/kg/day) Creatinine is a normal
waste product that the body produces every day during muscle movements and when
digesting meat. Healthy kidneys remove creatinine from the
blood, and it leaves the body in urine. High
levels of creatinine in the urine can indicate
diabetes, high muscle tone, or problems with the kidneys

Creatinine
is a normal waste product that the body produces every day during muscle
movements and when digesting meat. Healthy kidneys remove creatinine from the
blood, and it leaves the body in urine. typical ranges for creatinine levels in
a 24 hour urine sample in either grams per day (g/day) or mill moles per day
(mmol/day).
High levels of creatinine in the urine can indicate diabetes, high muscle tone, or problems
with the kidneys.
This
test reveals a person’s creatinine clearance rate, which is the amount of
creatinine that the kidneys process per unit of time.
Creatinine
levels vary throughout the day. Due to this, it is asdvisable to order a 24
hour urine sample test to get a more accurate measure of how much creatinine
the kidneys are clearing.
For
this type of urine test, the individual will need to collect all of the urine
that they produce over 24 hours. Then relative
will send the urine sample to a laboratory for analysis.
If
the amount of creatinine in the urine does not fall within the normal range,
this could indicate that the kidneys are not functioning properly. This
dysfunction may be due to kidney damage, kidney disease, or other health issues
that can affect kidney function.
However,
the amount of creatinine in a person’s body varies widely depending on race,
gender, age, and body size. This variation means that urine levels are a poor
indicator of kidney problems.
Serum
creatinine and GFR are the other tests . To test for serum creatinine, doctors
often use the glomerular filtration rate (GFR). A GFR test takes into account a
person’s age, race, gender, and body size when calculating creatinine levels.
The
levels of creatinine in urine vary based on a person’s age, sex, health
history, and muscle mass. Higher levels may not necessarily indicate.
,
normal ranges are as follows:
- for males, 0.8–1.8 g/day or 7.0–16.0 mmol/day
- for females, 0.6–1.6 g/day or 5.3–14.0 mmol/day
However,
the reference ranges may vary among laboratories. The person’s healthcare
provider should be able to review the numbers and explain what the results mean
and whether further tests are necessary.
What do high and low creatinine
levels mean?
When
a person’s urine creatinine levels do not fall within the normal range, this
could be a sign of an issue with their kidneys. However, high levels do not
always indicate a problem.
In
some cases, having a lot of muscle can cause high creatinine levels in the
body. Diets rich in protein can also lead to high creatinine levels.
Some
medical issues that can cause high or low creatinine levels include:
- kidney failure
- kidney
infection
- late stage muscular
dystrophy
- kidney disease
- myasthenia
gravis
- kidney
stones or other urinary tract obstruction
