Yes "Negative" is the reference range for occult blood
first of all, a good understanding of how the biochemistry of the body operates is required. However looking at the reference range is a good start, to see what is 'normal.' I use normal in inverted commas as a normal healthy person can have a result outside the reference range and a diseased patient can have a result within the reference range.
3.1 - 6.9 are the normal reference ranges for a random blood sugar test
The average Leukocyte count is [4-10]
the normal INR reading is 1.0 to 1.2. In some cases require thin blood to pass without difficulty in blood vessels, then normal range is 2.0 to 3.0
The normal count is 4 to 6 million red blood cells per cubic millimeter. - for adult males: 4,600,000-6,200,000 cells per mm3 - for adult females: 4,200,000-5,400,000 cells per mm3
This would be within the normal range for an adult diastolic resting blood pressure.
No. 103 is a good, low blood glucose reading that is well within the safe range. 103 is even acceptable for a morning or fasting reading.
A blood glucose measurement determines the amount of sugar or glucose in the blood. A normal blood sugar reading before eating is between 70 to 90mg/dL. Provided you did not have anything to eat prior to the test, your blood sugar level reading is in the normal range.
4.01 million red blood cells per decaliter (0.1 L) of blood plasma. A normal reading is generally considered to be 4.5-5.5, or as wide of a range of 4.2-5.8. A reading of 4.01 means a low level of red blood cells, meaning the subject is anemic.
It depends on the lab, but the normal range is usually from 0-50.
The reference range for the Modification of Diet in Renal Disease (MDRD) blood test is typically between 60-90 mL/min/1.73 m². This test is used to estimate the glomerular filtration rate (GFR) and assess kidney function. Results below this range may indicate kidney dysfunction or disease.
