The CD4/CD8 ratio is a blood test that measures the ratio between two types of white blood cells: CD4+ T-cells and CD8+ T-cells. These cells play a crucial role in the immune system by helping the body fight infections and stay healthy.
Testing the CD4/CD8 ratio is particularly useful for individuals with certain conditions that affect the immune system, such as HIV/AIDS. It helps assess immune health and monitor the effectiveness of HIV treatments.
The CD4/CD8 ratio helps assess the balance between these two cell types. A healthy ratio indicates a properly functioning immune system, while deviations may point to potential health issues or a compromised immune system.
A higher than normal CD4/CD8 ratio may indicate an effective immune response against infections or a good management of conditions such as HIV.
A low CD4/CD8 ratio may indicate a weakened immune system, which can increase the risk of infections and certain types of cancer. This is particularly important for individuals with HIV, as it may indicate disease progression or reduced treatment effectiveness.

After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.
