Notes for senders


The Institute of Medical Microbiology and Virology is responsible for the entire infection diagnostics in the patient care of the UMG and numerous external clinics. Depending on the problem, both classical methods of direct pathogen detection (microscopy and culture) and phenotypic resistance testing, as well as very modern molecular biological detection methods are used. For targeted investigations of risk organisms, the Institute of Medical Microbiology and Virology also has an S3 laboratory (e.g. tuberculosis) at the measuring site at Kreuzbergring 57, in accordance with the biosubstances ordinance. In addition, serological methods of antibody and antigen detection are performed.

Due to the expertise of the staff, new test methods are regularly developed or existing ones optimized. Associated with this, the Institute of Medical Microbiology has received international and national recognition and is currently a consiliary or expert laboratory for toxoplasmosis diagnostics appointed by the Robert Koch Institute.

Regularly conducted infection rounds, an Antibiotic Stewardship (ABS) team, and daily face-to-face telephone consultations are designed to provide even closer infectious microbiology care to university hospitals and external hospitals and to help limit nosocomial infections.

Regular Hours of Service:

Monday to Friday: 8.00 a.m. - 4.00 p.m.
Saturday: 8.00 a.m. - 1.00 p.m.

Sundays and holidays: NONE

Special opening hours may apply for certain holidays (e.g. Easter Monday, Whit Monday) and holiday constellations (e.g. Christmas/New Year). These will be announced in good time, e.g. on the intranet or homepage. The diagnostic laboratories are staffed at the times indicated and can be contacted for information by telephone. All microbiological test materials are accepted. Please note that outside the regular service hours the laboratory is not staffed. A medical on-call service is then available for medical emergencies.

Sample Vessels:


The microbiological sample containers approved for use at UMG by pneumatic tube mail can be found on the intranet at (UMG/06_Business Units and Staff Offices/G3-3Building Management/Tube Mail/Annex 4 Table - Material-Vessel Combination Suitable for Sample Shipping). All microbiology specimens in approved primary containers shall be packaged in the designated "MiBi bags" (Medical Microbiology Shipping Bag, Order No., 4048400) for onward shipment and addressing to the microbiology laboratory. Several samples per bag are permitted, however, microbiological samples must not be mixed with samples for other laboratory areas (e.g. clinical chemistry) in one bag.

External senders

Please use only the sample containers and packaging concepts agreed with us.


Specimen storage:

at room temperature (sensitive germ species can die at 4°C!)

  • Blood cultures
  • Aspirates / punctates of normally sterile body fluids including CSFs
  • Pus, (wound) secretions
  • Biopsies / tissue samples in 0.9 % NaCl solution.
  • Swabs and catheter tips in transport medium


at 4°C in the refrigerator

  • Examination material with accompanying flora (e.g. sputum, bronchial secretion, stool)
  • Test material in which the bacterial count is important (e.g. urine, BAL)
  • Serum for serological tests (preferably no whole blood!)

Sample transport from the UMG area:

Mondays to Fridays (routine hours):

Sample transport at routine times from the clinics (UBFT) to the measurement site at Kreuzbergring 57 of the Institute of Medical Microbiology and Virology is carried out via a complex system of telelift system, pneumatic tube, internal patient transport service (IKDT) and UMG driving service .Only a few wards at UMG have access to direct pneumatic tube transport of patient samples to the microbiology laboratory at Kreuzbergring 57 (e.g. INA). For most wards, therefore, transport of microbiological samples is via the telelift system to the sample distributor at the UMG laboratory measurement site at UBFT. At routine times , theMiBi bags with the contained samples are forwarded from there via the pneumatictube system to the Kreuzbergring 57 measurement site .For this purpose,all samples must be packed in accordance with the pneumatic tube system.
In addition, at the working day peak times (between 06:00 and 07:30 and between 13:15 and 13:45) ,an additional pneumatic tube-independent sample transport iscarried out directly to the Kreuzbergring 57 measuring site by the IKDT together with the driving service ata few specified collection points (e.g. level offices, INA, intensive care units, operating theaters) .

Saturday (routine times):

In addition to pneumatic tube transport, sample transport will take place at the collection points designated for Saturday between 09:45 and 10:30 (IKDT together with driving service).

Off-hours, Sundays and holidays (emergency rehearsals):

Outside routine hours, no samples are forwarded from the sample distributor in the UMG laboratory to the microbiology laboratory at Kreuzbergring .Emergency samples must therefore always first bearranged with the medical on-call service of Medical Microbiology and Virology .Afterwards, the transport of emergency microbiological samples is processed by the clinician via the UMG emergency transport software (Intranet: Forms:IKTD/Logbuch, for instructions see Quicklinks: Logbook Instructions, Tel: 62483 or 62484) will be organized.

Sample transport from the area external senders:

For peripheral senders, a network of transport services for laboratory samples exists.If you have any questions about sample transport and transport times for external senders,please call: 0551-39 65871.

Important notes on specimen shipment and infection control:

Please note that human diagnostic specimens constitute "infectious goods" and are subject to strict legal regulations and requirements during transport (ADR)!
For more detailed
information and assistance , please contact theUMGStaff Office for Safety and Environmental Protection.
Information and safety requirements for the transport of specimen materials by UMG pneumatic tube can be found on the intranet at:äftsbereiche und Stabsstellen/G33

Due to the legal requirements for the protection against infection, the transport of samples by service providers may only ever be carried out in special transport boxes.
Specimen materials that have been filled by the clinics into unsuitable specimen and transport containers, or are present in containers that are not tightly sealed, or have even or have even leaked, will not be transported by the employees of the transport services and will be left at the collection point!

Outside regular working hours, the Institute of Medical Microbiology and Virology is not staffed on site .For emergencies ,a medical on-call service is available formedical consultation or for the arrangement of urgent material approaches (reachable via thegate of the UMG (Tel. 0551-390; internal: 118)). Indications for emergency examinations outside the regular service hours are to be discussedcollegially with the microbiologist on duty.
Please note that the arrangement of examinations by the medical on-call service constitutes a request for a consultation!
