0.84-1.22
It is a ratio scale of measurement.
Examples are:a ratio can also show a part compared to the whole lot. For example there are 5 pups, 2 are boys and 3 are girls, then the ratio of boys to girls 2/3, the ratio of boys to total is 2/5, the ratio of girls to total is 3/5.a ratio can also be used in drawings. For example to draw a horse with a scale 1/10 from its normal size. Another example is that the height to width ratio of the Indian Flag is 2:3 or 2/3Another examples are:1/2, 3/4, 78/89, ... etcx/(x+1), y/(y-2), ... etc.
An F-statistic is a measure that is calculated from a sample. It is a ratio of two lots of sums of squares of Normal variates. The sampling distribution of this ratio follows the F distribution. The F-statistic is used to test whether the variances of two samples, or a sample and population, are the same. It is also used in the analysis of variance (ANOVA) to determine what proportion of the variance can be "explained" by regression.

The year is interval scale (no natural zero); your age is ratio.
Therapeutic range for aPTT is 45-75 seconds.
The normal range for activated partial thromboplastin time (APTT) is typically between 25-35 seconds. However, it can vary slightly depending on the laboratory's specific reference range. Outside of this range may indicate a bleeding disorder or a clotting factor deficiency.
1. INR (international normalised ratio) 2. aPTT
A blue-top tube (citrate tube) is used for collecting blood samples for the activated partial thromboplastin time (APTT) test.
Normal prothrombin time (PT) ranges from 11 to 13.5 seconds, while activated partial thromboplastin time (aPTT) typically falls between 30 to 40 seconds. The international normalized ratio (INR) is generally considered normal when it is around 0.8 to 1.1 for individuals not on anticoagulant therapy. These values can vary based on the laboratory and the specific testing methods used.
The color of the tube commonly used for APTT (Activated Partial Thromboplastin Time) is light blue.
aptt is 100 seconds
A low APTT result may suggest a bleeding disorder caused by factors like deficiencies in clotting factors (such as hemophilia) or the presence of inhibitors to clotting factors. Further evaluation is necessary to determine the specific cause of the prolonged APTT.
Partial thromboplastin time test results can be obtained in less than one hour.
