Q

What is the investigation of choice for G6PD deficiency?

A

G6PD enzyme activity one month after an attack.

People with G6PD deficiency are normally healthy, but must avoid these triggers. Certain triggers can cause red blood cells to be destroyed faster than they can be replaced (known as acute haemolytic anaemia or AHA). G6PD deficiency is diagnosed with a blood test.

Q

What specific test is used for anemia of chronic disease?

A

Increased ferritin levels.

Initial Test:
1. Complete Blood Count (CBC):
- The initial test for evaluating anemia is a CBC, which provides information on hemoglobin levels, hematocrit, and red blood cell indices. This helps to determine the presence and severity of anemia.

Best Test:
2. Serum Ferritin:
- The best test for diagnosing anemia of chronic disease is serum ferritin. Ferritin levels are typically normal or elevated in anemia of chronic disease, in contrast to iron deficiency anemia where ferritin levels are low. Elevated ferritin levels indicate adequate iron stores and help differentiate anemia of chronic disease from other types of anemia.

  • Serum Iron and Total Iron-Binding Capacity (TIBC): Low serum iron and low TIBC are characteristic of anemia of chronic disease.
  • C-Reactive Protein (CRP) and Erythrocyte Sedimentation Rate (ESR): These inflammation markers are often elevated in chronic diseases contributing to anemia.

For further detailed information, refer to the RACGP guidelines and relevant clinical resources:
