Testing for Low Iron Using an Orsense Finger Cuff
OneBlood has begun testing donors’ hemoglobin levels before blood donation by using the OrSense Finger Cuff. During this test, a cuff is placed around the finger, gentle pressure is applied and light is sent through the finger to provide a painless measurement of the blood levels.
This is considered to be a non-invasive method of testing iron or hemoglobin levels and may be preferred by those with a fear of needles.
What Happens When Iron Levels Are Low?
People who don’t have enough iron in their blood can lack energy and become tired easily. In addition, low iron levels in the blood affect the body’s ability to fight off illness, the brain’s ability to think clearly and the overall health of a person’s hair, skin and nails.
Potential signs of low iron include:
- Feeling short of breath
- A faster than normal heartbeat
- Cold hands and feet
- Hair loss or brittle nails
- Mouth sores
- Chewing ice
- Difficulty swallowing
