| Regular sample collection times | |
|---|---|
| Monday to Friday | 8:00am - 6:00pm |
| Saturday/Sunday/Public Holiday | 8:00am - 1:00pm |
Clinical patient samples are processed daily
In order to optimize diagnostic patient care, clinical patient samples are also processed on all Sundays and holidays, thus avoiding longer processing times for samples received by us on these days.The following diagnostics are also performed on all days:
- Microscopy of the following clinical samples: Blood cultures, cerebrospinal fluid (CSF)
- Cryptococcal antigen from CSF
- Legionella antigen from urine
- Pneumococcal antigen from urine
- Diagnostics for C.difficile toxin (PCR) from native stool
For the senders of the University Medical Center, this means informing the transport service electronically via "Logbuch" on Saturdays, Sundays and public holidays after sample collection, so that the samples arrive in our laboratory in a timely manner.
(Contact via the clinic headquarters Phone: +496131 17-0)
These samples can be deposited in the red emergency mailbox outside the regular sample collection times:
- this box can be found in the elevator area of the 8th floor of the high-rise building at the Augustusplatz (bldg. 905)
- please move the magnetic button to "sample inserted"
Report information
In SAP, the microbiological/virological preliminary and final findings can be accessed via the patient organizer, from where a cumulative report overview with antibiogram history is also possible in i/med.(Instructions: Findings view microbiology/virology (PDF 945,6 KB))
We are at your service:
- General questions - information on reports Phone: +496131 17-9158
-
If you have any questions regarding interpretation of findings, therapy recommendations, etc., please contact one of our physicians. A colleague can be reached on all working days between 08.00-18.45 at the Institute and outside these hours via the service telephone (contact via the clinic's central office 06131 17-0)

Direct preparation ("D-micro")
Definition: The direct preparation is a microscopic, gram-stained preparation that is prepared promptly from native material on the day the specimen is received.The following criteria must (!) be met:
The result of the direct preparation has therapeutic consequences (change of antimicrobial treatment according to microbiological recommendations).
The result of the direct preparation contributes to confirming the clinical diagnosis.
It is a primarily sterile patient sample.
With liquid samples: macroscopically purulent or clouded.
A maximum dose of one antimicrobial substance was administered.
Direct preparations are not recommended:
Under ongoing antimicrobial treatment.
If calculated antibiotic therapy has already been initiated.
With liquid patient samples that are macroscopically clear.
With removed foreign material/prostheses.
From heart valves.
During office hours ... it is sufficient to clearly indicate "D-Micro" on the request form. Corresponding stickers are available from our sample collection department (Phone: +496131 17-9158).
the preparation of a direct preparation is to be understood as an emergency consultation order. The microbiologist on call reserves the right to check the indication.
The employees of the sample transport service must be informed electronically via "Logbuch" by the sending department that the sample needs to be brought immediately to the Institute of Medical Microbiology as a registered direct preparation and will not be stored until the next day as is usually the case.
If the microbiologist on duty is not yet on site, a night mailbox (building 905, high-rise building at Augustusplatz, 8th floor next to the elevators) is available for placing the sample in. (Please adjust the magnetic button "Sample inserted")
Note on the speed of microbiological diagnostics
An examination can only begin once the patient sample has arrived at the laboratory!-
Rapid diagnostics: microscopic preparation, antigen detection if necessary
-
Cultural detection 24 - 48 hours (individual pathogens depending on the generation time up to several weeks), germ determination in positive blood cultures usually 2-4 hours after positive culture
-
Antibiogram / Respecific resistance mechanisms: another 24 hours each time
-
In principle, you will be informed by telephone and fax about relevant positive results (e.g. germ detection from primarily sterile patient samples).
