What Does a Sickling Test Measure?
A sickle cell screening test measures the presence of Sickle Cell Disease (SCD) or Sickle cell Trait. This test helps in diagnosing sickle cell trait.
In other words, it checks whether a person has the disease or can be a carrier and transmit the disease to their offspring. The test is generally conducted amongst newborns, but it can also be conducted amongst adults.1
Why Do Doctors Recommend a Sickling Test?
Though a sickle cell screening test can be carried out at any age, doctors mostly recommend it for newborn babies or to mothers while they are 8-10 weeks pregnant. Diagnosing sickle cell disease can be carried out in two ways2:
- Prenatal screening: This sickle cell blood test can be used for diagnosing sickle cell disease before a baby is born. In such cases, a sample of the amniotic fluid or tissue from the mother’s placenta is collected and checked for sickle cells. However, in prenatal screening, the doctors check for abnormal haemoglobin genes instead of haemoglobin S.
- Newborn screening: This kind of sickle cell screening is carried out just after birth, where a blood sample of the baby is collected and checked for the disease. It helps in diagnosing sickle cell trait and is also called a sickle cell anaemia test. The newborn sickle screening test also helps in determining whether the baby is a carrier of the disease.
Doctors can recommend a sickle screening test if you face any of the following symptoms3:
- Fatigue due to anaemia
- Paleness and shortness of breath
- Yellowing of the skin and eyes
- Periodic episodes of pain caused by blocked blood flow
- Hand-foot syndrome, resulting in swollen hands and feet
- Frequent infections
- Delayed growth
- Vision problems
