Standard 5: 100% of samples should be of adequate quality; repeats should be requested on no more than 2% of neonates (including all reasons)
| Results | 1996 | 1995 |
|---|---|---|
| Total number of neonates screened | 5017 | |
| Total number of samples screened | 5169 | |
| Insufficient sample to complete both tests | 42 (0.8%) | 0.8% |
| Sample contaminated (no results) | 7 (0.1%) | 0.1% |
| Sample unsuitable (delayed receipt) | 9 (0.2%) | 0.2% |
| Sample unsuitable (taken too early) | 36 (0.7%) | 0.3% |
| Unlabelled anonymous sample | 2 | |
| Total number of inadequate/unsuitable samples | 96 (1.9%) | 1.3% |
| Percentage of samples of adequate quality | 98.1% | 98.7% |
| Repeat samples requested by the laboratory | 70 (1.4%) | 1.1% |
| Total repeat samples received for all reasons | 1526-150 (2.9%) | 2.8% |
↵6-150 The discrepancy in this figure is because it includes several repeat samples sent while a neonate received total parenteral nutrition, transfers in/out of the district of sick inpatients. Other reasons for repeats included, for example, laboratory technical problems, mildly abnormal results and some received in the next financial year.
