Glossary

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.

cross-resistance – when resistance to one drug causes resistance to other similar drugs.

This commonly happens for every class or family of HIV drugs: nukes, NNRTIs, PIs, integrase inhibitors and entry inhibitors.

drug resistant mutation – a mutation or change that occurs in the HIV genome that reduces a drugs ability to work.

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.

primary HIV infection (PHI) – early infection (usually first six months with after HIV infection). Sometimes called acute infection.
