The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/(1.73 m 2) in men and 90–120 (mL/min)/(1.73 m 2) in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m 2 ) until 2 years of age in both sexes, and then it progressively decreases.
t. e. 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 ...
Upper limit of normal QT interval, corrected for heart rate according to Bazett's formula, [5] Fridericia's formula, [10] and subtracting 0.02 s from QT for every 10 bpm increase in heart rate. [13] Up to 0.42 s (≤ 420 ms) is chosen as normal QTc of QT B and QT F in this diagram. [14]

Reference range. In medicine and health -related fields, a reference range or reference interval is the range or the interval of values that is deemed normal for a physiological measurement in healthy persons (for example, the amount of creatinine in the blood, or the partial pressure of oxygen). It is a basis for comparison for a physician or ...
Volume of blood plasma delivered to the kidney per unit time. PAH clearance is a renal analysis method used to provide an estimate. Approximately 625 ml/min. renal blood flow = (HCT is hematocrit) Volume of blood delivered to the kidney per unit time. In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...
1.2 million (2015) [6] Chronic kidney disease (CKD) is a type of long-term kidney disease, in which either there is a gradual loss of kidney function which occurs over a period of months to years, or an abnormal kidney structure (with normal function). [2][5] Initially generally no symptoms are seen, but later symptoms may include leg swelling ...
The QTc is less than 450 ms in 95% of normal males, and less than 460 ms in 95% of normal females. LQTS is suggested if the QTc is longer than these cutoffs. However, as 5% of normal people also fall into this category, some suggest cutoffs of 470 and 480 ms for males and females respectively, corresponding with the 99th centiles of normal values.
