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 normal range for neutrophils in the blood is typically between 40-60%. This percentage may vary slightly depending on the specific laboratory reference range used for analysis.
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
This result indicates a positive reaction to lidocaine during the blood testing, suggesting a possible allergy to lidocaine. The reference range is 3.7, and a value of 49.0 exceeds this range, further supporting the presence of a potential allergic reaction to lidocaine in this individual. It is recommended to consult with a healthcare provider for further evaluation and management.
This would be within the normal range for an adult diastolic resting blood pressure.
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.
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.
A normal ALT (alanine aminotransferase) level in a blood test is typically between 7 to 56 units per liter. However, reference ranges may vary slightly between different laboratories. It's important to interpret the result in the context of the individual's overall health and medical history.
