A numeric result that is greater than the upper end of the reference interval will automatically flag as “H,” and a numeric result that is less than the lower end will automatically flag as “L.” Tests with a numeric result type for which no reference interval is defined in the LIS do not trigger any flags regardless of ...
If your blood counts fall outside of the normal range, which is shown in the “Reference interval” column, their values will be reported in the “Flag” column with an 'L' for low and an 'H' for high.
“H” means high value. “L” means low value. “HC” means “high critical” value. “LC” means “low critical” value. Any result values marked in this manner should be discussed with your health care provider, to better understand its significance as part of your overall health picture.
If a result in your thyroid function blood test is outside the normal range it can be flagged as high (H) or low (L). Interpretation of the many variations in test results is complex and an abnormal result may not mean that anything is wrong.
Flags: for paper results
On lab printouts, labs that are abnormal are indicated with a mark. There is often an empty column with marks identifying which rows contain abnormal bloodwork results. The mark may be an asterisk, or an "H" for high or "L" for low or "A" for abnormal.
For example, “H” next to a result may mean that it is higher than the reference range. “L” may mean “low” and “WNL” usually means “within normal limits.” Critical results. Those results that are dangerously abnormal must be reported immediately to the responsible person, such as the ordering physician.
And results that are outside the normal range (“abnormal”) don't mean a person has a disease. With some tests there is danger if the result is abnormally high or abnormally low. With other tests, it's worrisome only if the abnormality is in one direction.
In adults, normal levels for men range from 41%-50%. For women, the normal range is slightly lower: 36%-44%.
H and H: H and H, sometimes written as "H&H", is a popular shorthand for hemoglobin and hematocrit, two very common and important blood tests. Hemoglobin is the oxygen-carrying protein pigment in the blood, specifically in the red blood cells.
A high hemoglobin count occurs most commonly when your body requires an increased oxygen-carrying capacity, usually because: You smoke. You live at a high altitude and your red blood cell production naturally increases to compensate for the lower oxygen supply there.
Definition. By Mayo Clinic Staff. A high hemoglobin count indicates an above-normal level of the iron-containing protein in red blood cells. Hemoglobin (often abbreviated as Hb or Hgb) is the oxygen-carrying component of red blood cells.
Lab results are often shown as a set of numbers known as a reference range. A reference range may also be called "normal values." You may see something like this on your results: "normal: 77-99mg/dL" (milligrams per deciliter). Reference ranges are based on the normal test results of a large group of healthy people.
Regular blood tests can catch the warning signs of almost any disease early. Many heart, lung, and kidney conditions can be diagnosed using blood tests.
Physiological studies have shown that stress can affect the blood cell parameters1. These changes include increase in red blood cells, platelets and neutrophil count whereas eosinophils, lymphocytes and monocytes are said to decrease in number.
Blood tests can be used in a number of ways, such as helping to diagnose a condition, assessing the health of certain organs or screening for some genetic conditions.
The grading system consists of Honors (H), High Pass (HP), Pass (P), and Fail (F). The School employs a standard set of definition for each grade.
H Honors. Signifies outstanding work. No grade points are assigned. S Satisfactory. Signifies acceptable work.
Most blood tests aren't used on their own to diagnose cancer. But they can provide clues that may lead your health care team to make the diagnosis. For most types of cancer, a procedure to remove a sample of cells for testing is often needed to be sure.
Aside from leukemia, most cancers cannot be detected in routine blood work, such as a CBC test. However, specific blood tests are designed to identify tumor markers, which are chemicals and proteins that may be found in the blood in higher quantities than normal when cancer is present.
