There is no universally recognized reference value range for DLCO as of 2017, [10] but values in the 80%-120% of predicted range based on instrument manufacturer standards are generally considered normal. [11] A D LCO of less than 60% predicted portends a poor prognosis for lung cancer resection.
The therapeutic target range TSH level for patients on treatment ranges between 0.3 and 3.0 μIU/mL. [18] For hypothyroid patients on thyroxine, measurement of TSH alone is generally considered sufficient. An increase in TSH above the normal range indicates under-replacement or poor compliance with therapy.
Thyroxine-binding globulin (TBG) is a globulin protein that in humans is encoded by the SERPINA7 gene.TBG binds thyroid hormones in circulation.It is one of three transport proteins (along with transthyretin and serum albumin) responsible for carrying the thyroid hormones thyroxine (T 4) and triiodothyronine (T 3) in the bloodstream.
According to one lab test manual normal pH range is 7.2–8.2; [6] WHO criteria specify normal as 7.2–7.8. [5] Acidic ejaculate (lower pH value) may indicate one or both of the seminal vesicles are blocked.
The widely used [21] rule calculating normal maximum ESR values in adults (98% confidence limit) is given by a formula devised in 1983 from a study of ≈1000 individuals over the age of 20: [22] The normal values of ESR in men is age (in years) divided by 2; for women, the normal value is age (in years) plus 10, divided by 2.
Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies ...
An elevation in thyroid hormone levels is suggestive of thyroid storm when accompanied by signs of severe hyperthyroidism but is not diagnostic as it may also correlate with uncomplicated hyperthyroidism. [15] [18] Moreover, serum T3 may be normal in critically ill patients due to decreased conversion of T4 to T3. [15]
The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.
