Intended Use

The BioAid^® Hb pro Hemoglobin Microcuvette is specifically designed to work with the BioAid^® Hb pro Hemoglobin Meter to measure the hemoglobin concentration in capillary and venous whole blood. Microcuvettes are designed for professional in vitro diagnostic use only. They are intended for adults and children (≥ 2 years), not for newborns, and are to be used only outside the body.

Hemoglobin is the main component of red blood cells whose main function is to transport oxygen. The determination of hemoglobin concentration in whole blood is useful in the clinical diagnosis of diseases such as anemia and polycythemia. The measurement range of the BioAid^® Hb pro Hemoglobin Testing System is 0.0-26.0 g/dL.

HB pro Microcuvettes is designed for single use only, and it serves as both a pipette and a measuring cuvette. A blood specimen of approximately 8 μL is drawn into the cavity by capillary action. Measurement of the whole blood absorbance at the Hb/HbO₂ isobestic point is carried out on the meter.

The system consists of a meter together with microcuvettes. The microcuvette serves as both a pipette and a measuring cuvette which is designed for single use only. A blood specimen of approximately 8 μL is drawn into the cavity by capillary action. The meter measures whole blood absorbance at the Hb/HbO₂ isobestic point. It measures at two wavelengths (505 and 880 nm) to compensate for turbidity. Then it calculates and displays the hemoglobin level. The BioAid^® Hb pro Hemoglobin testing system is calibrated against the international reference method (HiCN), recommended by the ICSH for hemoglobin determination. It requires no further calibration.

Why To Test

1. What is a hemoglobin test?

A hemoglobin test measures the amount of hemoglobin in your blood. Hemoglobin is a protein that's the main component of red blood cells (erythrocytes). Hemoglobin contains iron, which allows it to bind to oxygen. Hemoglobin enables your red blood cells to carry oxygen from your lungs to other tissues and organs throughout your body.

The amount of hemoglobin you have, or your hemoglobin levels, provides clues about how healthy your red blood cells are. Knowing your hemoglobin level can help a healthcare provider diagnose blood disorders and other conditions. Hemoglobin tests are commonly used to diagnose anemia, which involves not having enough hemoglobin or healthy red blood cells.

2. Why is a hemoglobin test done?

Hemoglobin tests identifies the number of red blood cells in a blood sample. This information allows your provider to assess your health and screen for certain conditions.

You may perform a hemoglobin test if you have symptoms that suggest conditions related to low hemoglobin levels or high hemoglobin levels.

2.1 Low hemoglobin

Having low hemoglobin or too few red blood cells (RBC) can deprive your tissues and organs of the oxygen they need to make energy and keep you healthy.

Symptoms of low hemoglobin include:

● Fatigue.

● Pale skin (pallor).

● Weakness.

● Dizziness.

● Shortness of breath.

● Cold hands and feet.

2.2 High hemoglobin

Having high hemoglobin or too many red blood cells can cause your blood to thicken and become sluggish. Thick blood doesn't flow as quickly, depriving your organs of oxygen.

Symptoms of high hemoglobin include:

● Headaches.

● Blurred or double vision.

● Dizziness.

● Itching.

● Blood clots.

3. What do the test results mean?

A hemoglobin test can show if your levels are too low, as with anemia, or too high. It can also show how severe your condition is. It can't detect what's causing your abnormal levels.

Your healthcare provider will consider your hemoglobin levels alongside other test results to make a diagnosis.

4. What level of hemoglobin is normal?

The normal range for hemoglobin levels is 12 g/dL to 17 g/dL of blood for adults. However, levels may vary depending on your age, race and sex.

Factors related to your lifestyle and environment can also cause you to have abnormal levels, including:

● Altitude.

● Your diet.

● Exercise or physical activity.

● Medications you're taking.

5. What do low hemoglobin levels mean?

Lower than normal hemoglobin levels, or anemia, may be a sign that your body isn't producing enough red blood cells. Low levels may also signal that your red blood cells are being destroyed faster than they're made (hemolytic anemia). Chronic (long-lasting) blood loss also leads to a drop in hemoglobin levels. It's one of the most common causes of anemia.

Low hemoglobin levels may be a sign of:

● An iron deficiency.

● A nutrient deficiency (for example, vitamin B12 or folic acid).

● Cancers that affect your blood or bone marrow.

● Thalassemia.

● Kidney disease.

● Liver disease.

● Sickle cell disease.

● Autoimmune diseases.

● Blood loss resulting from surgery, injury, menstrual bleeding or bleeding from your gastrointestinal tract.

6. What do high hemoglobin levels mean?

Some conditions increase your number of red blood cells, causing too much hemoglobin in your blood. If you're dehydrated, your hemoglobin may be high because you have too many red blood cells in relation to your blood volume.

High hemoglobin levels may be a sign of:

● Polycythemia vera.

● Congenital heart defects.

● Certain types of kidney diseases, including kidney cancer.

● Lung disease, including chronic pulmonary obstructive disease (COPD) and pulmonary fibrosis.
