What is the hemoglobin test?

The hemoglobin test is a blood test that is used to determine how much hemoglobin the patient has in his body. This test is usually performed as part of complete blood numbers, a routine screening that controls the levels of a number of blood components. The levels of hemoglobin, which differ from the standard, may indicate a wide range of health problems and this test can be a very useful diagnostic tool. In addition, people can use hemoglobin tests to monitor the progress of various health conditions such as anemia.

Hemoglobin is a protein that naturally occurs in the blood. It performs a number of functions, but one of the most important is the transport of oxygen throughout the body. In adults, hemoglobin levels are between 12 and 18 grams per Decaliter, while the levels are lower in pregnant women. Children tend to have between 11 and 16 grams per decatalite. It is possible for a hemoglobin test to reveal numbers that may be higher or lower than Nerm.

low levels in hemoglobin test may indicate the presence of problems such as anemia and malnutrition, while high levels are associated with things such as dehydration and heart disease. It is also possible to test the hemoglobin itself and learn more about the patient's condition. For example, glycated hemoglobin or A1C test controls the amount of blood glucose, an indicator of poorly managed diabetes or increased risk of developing diabetes.

For the hemoglobin test, the blood sample is taken from the patient and passes the centrifugal to separate the primary components of the blood so that they can be analyzed. If several tests have been ordered, multiple blood bottles may be carried out, so only one needle is needed to collect all samples. Once the blood is analyzed, a printed message is prepared for the doctor, so that, or she can use information to evaluate the patient's condition and create a treatment plan.

Many things can change hemoglobin levels. For exampleLad levels tend to change throughout the day, which is an important consideration if someone has an unusually low or high number, but feels different healthy. Talking with the patient before ordering the test, the physician may get an idea of ​​the general patient's condition and use this information to evaluate the results of the hemoglobin test.
