Gastric Lavage
Conformément au Règl. de l’Ont. 671/92 pris en application de la Loi sur les services en français, l’information sur la commande de tests et les instructions connexes fournies sur la présente page sont disponibles en anglais seulement parce qu’elles sont de nature scientifique ou technique et qu’elles sont destinées à l’usage exclusif des fournisseurs de soins de santé qualifiés et non des membres du public.
This instruction is for the use of one gastric lavage kit for Mycobacterium culture, which includes a sterile container containing 0.75 ml of 38% Disodium phosphate (acid neutralizer) and indicator dye.
NOTE: It is ideal to collect fasting early-morning specimens on three consecutive days. When collecting specimens over three consecutive days, a separate gastric lavage kit is required for each day. Collect each specimen in the morning soon after patient awakens to obtain sputum swallowed during sleep.
Instructions:
- Open the pouched seal pack and aseptically remove the sterile container from the package.
- Add the specimen to the container and swirl the specimen in the container in order to neutralize the acidity.
Note: Specimen added should not exceed 25 ml. - Replace the cap on the container, ensuring it is tightly closed.
- Label the specimen container with the patient’s full name, date of collection and one other unique identifier such as the patient’s date of birth or Health Card Number. Failure to provide this information may result in rejection or testing delay.
- Complete all fields of the General Test Requisition: include, the patient’s full name, date of birth, Health Card Number (must match the specimen label), enter ‘Mycobacteria Culture’ under test description, source of specimen, date of onset, date of collection, physician name and address, and clinical diagnosis.
- Place specimen container in a biohazard bag and seal bag.
- Insert the completed requisition in the pocket on the outside of each sealed biohazard bag.
- Repeat steps 2 - 8 for specimens collected on the second and third days.
- Transport collected specimen(s) to the laboratory as soon as possible after collection. If transport is delayed more than one hour the specimen must be refrigerated.
- For further information about Mycobacteria culture testing refer to the Test Directory Index.
Storage of unused kits:
The kits can be stored at room temperature with stated expiry date - DO NOT USE EXPIRED KITS.
