Name of Test:
1. BUN (Blood Urea Nitrogen)
Normal Values:
Normal value = 7-25 MG/DL
Dialysis normal = 40-85 MG/DL
(values
will vary depending on protein intake)
Causes of Abnormal Values: Causes of abnormal levels
(refers to increases in):
- eating too much protein containing food
- could indicate need for more dialysis time
- could indicate need for higher blood flow rate
- could indicate need for a larger dialyzer
Signs and Symptoms:
Signs and symptoms associated with abnormal
levels:
- fatigue
- nausea
- insomnia
- dry and/or itchy skin
- urine-like body odor and/or breath
- taste and smell (senses) could be affected
Name of Test: 2. Calcium (Ca)
Normal Values:
Normal value = 8.5-10.8 MG/DL Dialysis normal = (Same) 8.5-10.8 MG/DL
Level is best near upper end to avoid overactive parathyroid glands.
Causes of Abnormal Values:
Causes of abnormal levels:
LOW:
- eating too much high phosphorus food
- not taking phosphorus binders as recommended
HIGH:
- medications such as Rocaltrol and/or Calderol may cause sharp increase.
- parathyroid gland removal may be indicated.
Calcium level will rise as phosphorus level
decreases.
Signs and Symptoms:
Signs and symptoms associated with abnormal
levels

blood values, the result should not exceed 70. For example, if your calcium level were 10 and you phosphorus lever were 8,
then you would have a Calcium PhosphateProduct of 80. This would be much too high. Some physicians even feel that a calcium
phospate product of below 50 is desirable.

Name of Test: 5. Creatinine
Definition of Creatinine/Creatinine Clearance:
Serum creatinine level and "creatinine clearance" are different ways
of determining kidney function. Creatinine is a protein produced by muscle and released into the blood. The amount produced
is relatively stable in a given person. The creatinine level in the serum is therefore determined by the rate it is being
removed, which is roughly a measure of kidney function. If kidney function falls (say a kidney is removed to donate to a relative),
the creatinine level will rise. Normal is about 1 for an average adult. Infants that have little muscle
will have lower normal levels (0.2). Muscle bound weight lifters may have a higher normal creatinine.
Creatinine clearance is technically the amount of blood that is "cleared"
of creatinine per time period. It is usually expressed in ml per minute. Normal
is 120 ml/min for an adult. It is roughly, inversely related to serum creatinine: If the clearance drops to one half of the
old level, the serum creatinine doubles (in the steady state). So for an adult, serum creatinine of 2 is roughly a creatinine
clearance of 60 ml/min; creatinine 3 is roughly a clearance of 30; creatinine of 4 is roughly a clearance of 15, etc. So why
didn't the creatinine rise to only 2 when a kidney was removed? (I said it would rise to 1.8) The answer is that the remaining
kidney "hyperfilters" and seems to work harder, therefore kidney function is not quite halved.
Usually, an adult will need dialysis because symptoms of kidney failure
appear at a clearance of less than 10 ml/min. Creatinine clearance has to be measured by urine collection (usually 12 or 24
hours). It is a more precise estimate of kidney function than serum creatinine since it does not depend on the amount of muscle
one has.
Note that the units used in the United States are milligrams per deciliter (mg/dl). To convert to international
units (micromoles per liter) multiply the creatinine (in mg/dl) by 88. Thus a serum creatinine of 2mg/dl is the same as 176
micromoles per liter.
Normal Values:
Normal value = less than 1.5 MG/DL
Accepted dialysis normal = 10-20
MG/DL
Varies with muscle mass. Elderly may have lower creatinine due to loss
of muscle mass. Type II Diabetics have an acceptable range of 4-6 MG/DL. Should remain about the same as at start of dialysis
from treatment to treatment. Only the most muscular of individuals should have values in the upper range. Desirable levels
are in the low teens.
Causes of Abnormal Values:
Causes of abnormal levels:
- inadequate "real" dialysis time
- increase in muscle mass
Signs and Symptoms:
Signs and symptoms associated with abnormal
levels:

monitored with special attention to unsteady values. Any changes, especially increases, should be discussed with your care

Name of Test:
10. Sodium (Na)
Normal Values:
Normal value = 135 - 147 MEQ/L
Dialysis normal = Same 135 -147 MEQ/L
Causes of Abnormal Values:
Causes of abnormal levels:
- eating too much salt (found in canned vegetables, potato chips, bacon,
etc.)
- High sodium levels in diaysate
Signs and Symptoms:
Signs and symptoms associated with abnormal
levels:
- thirst - leads to drinking more fluids and results in fluid weight
gain
- elevated blood pressure (hypertension)
- shortness of breath
Note: Lower levels in your dialysate will
cause you to be less thirsty. But lower levels will also lead to lower blood pressure. As long as your blood pressure will
stay high enough to tolerate them, constnat dialysate levels as low as 135 to 137 will significantly reduce thirst.
(If you are to tolerate such low levels
you must limit your weight gain to 3 or 4 pounds between treatments. Lowering your weight gain may seem almost impossible
if your blood sodium is high already. It is much easier once your blood levels become lower)
While gradually lowering sodum levels during
diaysis ("sodium modeling") is better than high levels during the entire run, constant low levels during the run are even
better in allowing you to leave the dialysis session with a low level of sodium in your body and thus a resulting decrease
in thirst between treatments.
