PATHOLOGY TEST AND LAB

VIT D levels
  • Vitamin D is a family of compounds that is
    essential for the proper growth and formation of
    teeth and bones. This test measures the level of
    vitamin D in the blood.
  • Two forms of vitamin D can be measured in the
    blood, 25-hydroxyvitamin D and 1,25-dihydroxyvitam
    in D. The 25-hydroxyvitamin D is the major form
    found in the blood and is the relatively inactive
    precursor to the active hormone,
    1,25-dihydroxyvitamin D. Because of its long
    half-life and higher concentration,
    25-hydroxyvitamin D is commonly measured to
    assess and monitor vitamin D status in
    individuals.
  • Adequate sun exposure is typically estimated to
    be two periods per week of 5-20 minutes. People
    who do not have adequate sun exposure may obtain
    the vitamin D that they need from food sources or
    supplements.

Total Protein Hours Urine Biochemistry
  • The urine protein test measures the amount of
    protein being excreted in the urine. There are
    several different kinds of urine protein tests. A
    semi-quantitative protein dipstick is
    frequently performed as part of a urinalysis,
    generally on a random urine sample. The quantity
    of protein in a 24-hour urine sample may be
    measured and reported as the amount of protein
    excreted per 24 hours. Also, the amount of
    protein in a random urine sample may be measured
    and reported as the ratio of protein to
    creatinine.
  • The presence of albumin in the urine
    (albuminuria) has been shown to be a good
    indicator of kidney disease in patients with
    diabetes and with high blood pressure. Therefore,
    most of the time the doctor may test specifically
    for albumin, as opposed to total protein in the
    urine.
