What we do
The Phlebotomy Department provides blood tests on a walk-in basis. We carry out a wide range of tests including testing for lipids, cholesterol, triglycerides, gut hormones, fasting blood sugar, malaria and drug monitoring. The department is based on two sites: King’s main site at Denmark Hill and Dulwich Community Hospital.
King’s College Hospital
Primarily for patients referred by King’s College Hospital but also open to GP patients. The unit operates Monday to Friday, 7.30am-5.45pm. It is closed on bank (public) holidays.
Dulwich Community Hospital
We run a satellite unit at Dulwich Community Hospital providing a blood test service mainly for GP patients. The unit operates Monday to Friday, 7.30am to 3.45pm. It is closed on bank (public) holidays.
