Quality control


QUELAB LABORATORIES INC. has been involved in the production of dehydrated and prepared culture media and other diagnostic products since 1978. Prepared ready to use biological culture media are manufactured according to the Quality Assurance Procedures published by the National Committee for Clinical Laboratory Standards.

QUELAB LABORATORIES'quality control department is staffed with qualified a nd well-trained technicians under expert supervision. Each lot of finished products is clearly identified, and tests results and observations are recorded and filed for easy referral. Certificates of analysis are obtained upon written request.

Raw materials are obtained from reputable suppliers and are tested in our Quality Control Laboratories prior to use.

All animal products (blood, sera) come from herds that are constantly supervised for general health conditions, food and shelter. The blood from each animal is first sterility-tested and then standardized by hematocrit.

Representative samples of each lot of our various finished products are tested for homogeneity pH, clarity, vacuum, sterility and performance as required:

The general aspect, color and volume (depth or thickness) of the media must be uniform. Products must be free of particulate or foreign matter, as well as of bubbles and clumps which may interfere with results.

Each lot of product must be within a pre-determined pH range, and is controlled electrometrically

Each medium is visually inspected and must have the expected clarity for its type and composition

Verification of a representative number of blood culture bottle.

Incubation in optimal conditions of representative samples to isolate any eventual contaminants (bacterial or fungal). As for the media used for haemoculture, the samples are incubated at 35C for seven (7) days and at room temperature for twenty-one (21) days.

Verification of the capacity of each media to encourage or inhibit the growth of the given microbes. A representative number of samples from each lot are cultured with diluted and concentrated suspensions with a number of bacterial colonies from A.T.C.C. (American Type Culture Collection) and from recent clinical specimens. After incubation in proper conditions, caracteristic growth, haemolytic reactions or biochemical reactions are rigourously evaluated and compared to the established norms.

In the case of media for haemoculture, randomly picked bottles from each lot are cultured with the help of blood donor set with the following germs diluted in defibrinated sheep blood: Staphylococcus aureus (coagulase positive), Streptococcus pyogenes, Neisseria meningitidis, Bacteroides fragilis, and Haemophilus influenzae. After the appropriate incubation period, the bacterial growth is evaluated qualitatively by macroscopic observation and transfer to a selective media. The identity of the germs is confirmed.

Only the lots witch correspond to the highest Quelab's norms are liberated by our Quality Control Department.




Quality control certificate


QUELAB LABORATORIES INC. supplies with every shipment two packing slips; the one printed "CERTIFICATE" certify that performance for the shipped lot meets N.C.C.L.S. and QUELAB specifications.

If a detailed Quality Control Certificate is required, when placing order add to the product code,the two letters QC (ex: 1517QC).






QUELAB LABORATORIES' Quality Control Department recommends specific storage conditions for the optimal shelf-life of our products, and determines the expiry date for each lot:

  1. Plate media should generally be refrigerated (2-8C) and kept in the dark. The expiry date printed on each package label applies only to intact shrink wrap packages.
  2. Tubed and bottled media may usually be kept at room temperature (20-22C) and kept in the dark. However, blood and antibiotic-containing media must be refrigerated (2-8C) and kept in the dark. All these media have an expiry printed on each label.
  3. Animal blood and sera must be refrigerated (2-8C) and kept in the dark.
