CD4% – percentage of total lymphocytes (white blood cells) that are CD4 cells.
The CD4% is generally more stable than the CD4 count. For example, if you ever get a CD4 count that is much lower than you expect, first see whether the CD4% has changed too,
If the CD4% is still roughly the same then the low CD4 count is unlikely to show a real change.
internal fetal labour monitoring – where an electrode is inserted through the vagina and placed on the baby’s scalp to record the baby’s heart rate during labour.
chorioamnionitis is an inflammation of the membranes that surround the foetus (called the chorion and the amnion). Chorioamnionitis is usually caused by a bacterial infection.
clinical cut-off (CCO) – a test result that is associated with an impact on clinical care. With resistance tests a lower CCO is the level below which a drug is still sensitive or active. This is often set at a 20% loss of activity (compared to wild-type HIV). An upper CCO is the level above which the drug is not considered active (ie resistant). This is often set at an 80% loss of activity (compared to wild-type HIV).
protozoa – a single-celled animals that are larger and more complex than bacteria.
