If transport is delayed, samples can be stored at ambient room temperature for up to 24 hoursGeneral Information
Samples dispatched to the laboratory in sputum traps which have not been sealed with a screw cap are unsafe for portering and laboratory staff!
Salivary samples are unsuitable for testing.
Sputum samples received in the laboratory for culture are not routinely examined for Mycobacterium tuberculosis. When tuberculosis is suspected, it is essential to indicate this on the request form so that staining, culture (and PCR where relevant) for Mycobacterium tuberculosis can be carried out. Samples for Mycobacterium tuberculosis will be referred to Heartlands. Quantiferon for latent TB infection is performed by immunology. Rapid TB testing turn-around time is 24 hours.
Broncho-alveolar lavages, (BAL) and pleural fluids may be sent in sterile universal containers. If urgent processing is required notify the laboratory using extension number 16534 during normal working hours or via switchboard at other times.
Information Sharing: If your sample needs to be referred or a notifiable disease is detected from your sample, your details and sample may be shared with the UK Health Security Agency (UKHSA). This is a legal requirement. The UKHSA is sponsored by the Department of Health and Social Care.
