Our Services
Our clients have different needs. If they are using water for life sustaining haemodialysis or whether they want to test drinking water we discuss their needs and provide the tests they want.
230023 - Dialysis Water Testing
HSL provides a water testing service to hospitals and patients with home dialysis units. The service includes total viable cell counts (TVC) and Endotoxin levels together with periodic measurement of metals present.
The quality of the water is judged against the criteria specified in Clinical Practice guidelines (5.2 and 5.3) Microbiological contaminants in product water used for the preparation of dialysis fluid. UK Renal Association and Renal Transplantation.
Low flux dialysis water should contain TVC count of less than 100 CFU/ml and an endotoxin concentration of less than 0.25 EU/m. High flux dialysis water should contain a total viable count of less than 0.1 CFU/ml and an endotoxin level of less than 0.03 EU/ml.
230030 - Drinking Water Testing
We can carry out analysis of coarse particles and gelatinous material. HSL will test for the presence of Pseudomonas aeruginosa and legionella.
Individual Services
HSL carries out routine microbiological tests for bacterial contamination, specialist tests for legionella and pseudomonas as well as tests for metals required by water quality standards.
230024 - Legionella
HSL will collect water samples and the test will be carried out in a UKAS approved laboratory
230025 - Pseudomonas
Water samples are tested for the presence of Pseudomonas by plate culture method.
230026 - Total Viable Microbial Counts (TVC)
Enumeration of total viable cells from 1 ml of water sample using plate culture method.
230027 - Endotoxins
The presence of endotoxins is measured by the limulus Amoebocyte lysate turbidimetric method (LAL)
230028 - Metals
We can routinely test for most metals including -calcium, potassium, magnesium, sodium and the isotopes 9Be, 27AL, 52Cr, 65Cu, 66ZN, 75As, 82Se, 107Ag, 111Cd, 121Ba, 202Hg, 205Ti and 208Pb.
230025 - Chlorine testing
HSL can carry out weekly chlorine testing according to the Clinical Practice Guidelines 4.1-4.4, UK Renal Association and Renal Transplantation.
WHO (World Health Organization)More than half a million people are estimated to die
each year from diarrhoea as a result of unsafe drinking-water
