Fasting is not typically required for a hemoglobin and hematocrit test. These tests measure the levels of red blood cells in the blood and do not require fasting for accurate results.

If you had a hemoglobin of 12.0 what is expected range of you hematocrit?

The expected range for hematocrit is 3 times the hemoglobin level, so with a hemoglobin of 12.0 g/dL, the expected hematocrit range would be around 36-40%.


If you have a high hemocrit would your hemoglobin be high or low?

If you have a high hematocrit, your hemoglobin levels would likely be high as well. Hematocrit measures the volume of red blood cells in blood, while hemoglobin is the protein that carries oxygen in red blood cells. An increase in hematocrit often corresponds with an increase in hemoglobin levels.


What if you have a hemoglobin of 16.5 and hematocrit of 47.6?

A hemoglobin of 16.5 and hematocrit of 47.6 are within normal ranges for adults. These values indicate that your blood has sufficient oxygen-carrying capacity. However, it's always best to interpret these results in the context of your overall health and symptoms with the help of a healthcare provider.


What blood test includes wbc and rbc counts hemoglobin and hematocrit?

A complete blood count (CBC) includes white blood cell (WBC) and red blood cell (RBC) counts, hemoglobin, and hematocrit measurements. It provides important information about your overall health and can help diagnose various medical conditions such as anemia, infection, and inflammation.


Which blood measurements provide information on a possible anemic condition?

Hemoglobin levels, hematocrit levels, and red blood cell count are blood measurements that can provide information on a possible anemic condition. Anemia is often characterized by low levels of these parameters.

If you had high hematocrit would your hemoglobin be high or low?

RBCs are made up of hemoglobin, therefore if the hematocrit is high you should expect a high hemoglobin determination.

What is the approximation of hemoglobin in the hematocrit?

Typically between 30% and 40%.


Do hematocrit and hemoglobin content of blood measure the same thing?

Hematocrit and hemoglobin content of blood measure are not the same thing. The hematocrit, also known as the HCT, is the percentage of RBC in the blood volume. Hemoglobin, on the other hand, also known as HGB, is the measurement of protein in the blood.


What causes blood transfusionor low blood pressure?

If you have a low blood pressure, low hematocrit and hemoglobin, you need to have a blood transfusion.


What is the proper Units of measurement for hemoglobin and hematocrit results?

g/dL


How do you calculate MCHC?

MCHC (Mean Corpuscular Hemoglobin Concentration) is calculated by dividing the total hemoglobin by the hematocrit value and then multiplying by 100. The formula is: MCHC = (Hemoglobin / Hematocrit) * 100. This measurement is useful in assessing red blood cell health and hydration status.


What are the proper units of measurement for reporting hemoglobin and hematocrit results?

gm/dl; GRAMS of hemoglobin that are present in a DECILITER of a blood sample


What clinical setting has normal hemoglobin and low hematocrit?

Hematocrit is a percentage, so low hct with normal hgb levels could mean overhydration.


Which laboratory finding is indicative of anemia?

Low hemoglobin and low hematocrit are indicative of anemia.
