However, abnormal levels of haemoglobin, that is, low or high haemoglobin, does not necessarily imply a serious medical condition that needs to be treated. It can occur due to monthly menstrual cycle in women and/or the result of iron-deficient diet and other lifestyle habits. A daily diet rich in iron, regular physical activities, and iron supplements are usually effective in maintaining the normal level of haemoglobin.

When should the Haemoglobin Test be Repeated?
The haemoglobin test is usually repeated at regular intervals to assess the level of haemoglobin. For evaluation of certain medical conditions or to monitor the treatment of some medical conditions, the doctor may advise repeating the test regularly. Follow the doctor’s advice.
Procedure for the Haemoglobin Test
For the Hb test, a blood sample is drawn from any of the following parts of the body:
- Vein for children and adults
- Fingerstick for children and adults, or
- Heelstick for newborns
The healthcare expert selects the location from where he/she will draw blood and applies an antiseptic solution to clean the area. The needle is then inserted into the vein to draw blood, which is then collected in the vial of the injection. A cotton swab is used to soak the blood from the puncture and then covered with a bandage. The entire process usually does not take more than 5 minutes. The bandage can be disposed of after about 10 minutes or as advised by the healthcare expert. The blood sample is sent to a laboratory for microscopic analysis to evaluate the haemoglobin level.
