Pathology tests directory

Our tests directory below includes information to support you to take and submit blood transfusion, chemical pathology, haematology, immunology, bacteriology, virology and other microbiology tests.

All testing is performed within the trust unless otherwise stated.  If the required test is not listed, please contact the microbiology laboratory for guidance.

Please note: when printed, this information is only valid on the day of printing.

Reference ranges given are for general guidance. Results falling outside the reference range do not necessarily indicate underlying pathology. 

Where a colour is given for the top of a sample tube, this applies only to adult size Vacutainer® tubes. Paediatric size and other manufacturers use different colour coding.

Please contact the laboratory if you need advice regarding paediatric specimens.

Mycoplasma total antibody (IgG and IgM)

Specimen

A minimum of 5-10 ml of clotted blood is required. Take two samples if several tests requested.Smaller samples are accepted on paediatrics however sample volume will determine how many tests can be performed.

Bottle top colour

Blood tube: gold top or red top (vacutainer)

Bottle / container

Photo of Mycoplasma total antibody (IgG and IgM)

Turn around time

1-5 working days

Performed (frequency)

Twice weekly

Transport and storage

Transport to the laboratory immediately in a sealed specimen transport bag with an accompanying request form. If there is a delay or the sample is taken out of hours store it at 4-8 *C if not urgent and send immediately the following day. Do not store the sample for >24Hrs as this may effect the performance of the test or the interpretation of the results.

Additional information

In addition to relevant clinical details, it is important to state the date of onset of symptoms. A convalescent serum 10-14 days later may be needed.If no test is clearly requested AND no clinical details are clearly stated on the request form the sample will be stored.

This test detects the presence of anti-Mycoplasma pneumoniae antibody. It does not detect Mycoplasma pneumoniae directly. Therefore, a positive result does not indicate a conclusive Mycoplasma pneumoniae infection diagnosis.

There is a possibility that an extremely low concentration of the antibody cannot be detected by this test. In some patients infected with Mycoplasma pneumoniae, antibodies are not produced or a very small amount of antibodies are produced. a comprehensive assessment of the patient’s condition should comprise the careful analysis of the patient’s clinical symptoms and interpretation of results of available tests for the disease.

Note that some specimens with very high antibody titre may exhibit the prozoning phenomenon at lower dilutions.

Some samples may react non-specifically with the unsensitised particles in this assay. These samples will need further treatment before a result can be established, which may lead to a longer than stated turnaround time for results.
