This is termed the albumin/creatinine ratio (ACR) [10] and microalbuminuria is defined as ACR ≥3.5 mg/mmol (female) or ≥2.5 mg/mmol (male), [11] or with both substances measured by mass, as an ACR between 30 and 300 μg albumin/mg creatinine. [12] For the diagnosis of microalbuminuria, care must be taken when collecting sample for the urine ...
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
Reference ranges for urine tests are described below: Measurement Lower limit Upper limit ... 0 / negative [2] White blood cells (WBCs) 0 [2] 2 [2] pH: 5 [2] 7 [2 ...
False negative readings can occur when testing is done too early. hCG levels rise rapidly in early pregnancy and the chances of false negative test results diminish with time (increasing gestational age). [24] Less sensitive urine tests and qualitative blood tests may not detect pregnancy until three or four days after implantation. [25]
Creatinine(U)] is taken into account due to the notion that creatinine is normally released into the urine at a constant rate. [6] Scientists found that the ratio of protein to creatinine roughly estimates the actual value gained from the 24-hour urine protein test. [6] The normal urine protein/creatinine ratio is less than 200 mg/g. [7]
As an example, Alpha-fetoprotein (AFP) testing is used to screen for a neural tube defect (NTD) during the second trimester of pregnancy. If the median AFP result at 16 weeks of gestation is 30 ng/mL and a pregnant woman's AFP result at that same gestational age is 60 ng/mL, then her MoM is equal to 60/30 = 2.0.
Urine electrolyte levels can be measured in a medical laboratory for diagnostic purposes. The urine concentrations of sodium, chlorine and potassium may be used to investigate conditions such as abnormal blood electrolyte levels, acute kidney injury, metabolic alkalosis and hypovolemia.
