Overview
The IDDSI Liquid Flow Test Log is an inspection record for verifying the thickness of beverages and other liquids using the 10 mL syringe flow test. It captures the inspection date and time, who performed the test, where the sample was prepared, the intended IDDSI level, the test setup, the measured volume remaining after 10 seconds, and the final classification. It also provides space for corrective action, hold/release decisions, retesting, review, and sign-off.
Use this template when your operation serves drinks that must meet a specific IDDSI level, such as Level 0 Thin through Level 3 Moderately Thick. It is useful for batch production, tray line checks, bedside or unit-level verification, and any situation where temperature, mixing, or hold time could change the result. The log is especially helpful when multiple staff members prepare the same beverage or when a recipe uses a thickener that can settle, separate, or continue to hydrate after mixing.
Do not use this log as a substitute for clinical swallowing assessment or as a generic beverage quality note. It is not meant for drinks that are not being controlled to an IDDSI target, and it should not be used to guess at a level without performing the actual flow test. If a result is borderline, inconsistent, or outside the intended range, the product should be held, adjusted, and retested before service. The template is designed to leave a clear record of what was tested, what was found, and what action was taken.
Standards & compliance context
- This template supports IDDSI-based texture and thickness control commonly used in healthcare foodservice and aligns with facility policies built around safe swallowing practices.
- Where your organization uses formal quality systems, the log can function as objective evidence for ISO 9001-style process control and non-conformance handling.
- If your operation is part of a regulated care environment, the record helps demonstrate that food and beverage preparation followed documented procedures and review steps.
- For facilities with clinical oversight, supervisor or dietitian review provides a clear escalation path for borderline results and recipe changes.
- The template is not a clinical diagnosis tool and should be used alongside your care plan, diet order, and local policy for modified liquids.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Inspection Details
This section identifies exactly what was tested, where, and by whom so the result can be traced back to the correct beverage and service area.
- Inspection date and time recorded
- Inspector name or role documented
- Location or service area identified
- Intended beverage or recipe name documented
- Target IDDSI level selected
Test Setup and Conditions
This section proves the test was run under the right conditions, which matters because syringe position, mixing, and temperature can change the result.
- 10 mL syringe used for the flow test
- Syringe positioned vertically and test started with thumb over nozzle
-
Liquid tested at serving temperature
Confirm the sample was tested at the temperature it will be served, since viscosity may change with temperature.
- Sample mixed uniformly before testing
- Test performed on a representative sample
Flow Test Result
This section captures the measured outcome and the IDDSI level so the log shows the actual classification, not just a subjective judgment.
- Volume remaining in syringe after 10 seconds
- Measured IDDSI level based on flow result
- Result matches intended target level
- Flow test completed within the expected 10-second interval
Classification and Corrective Action
This section records what happened after the result was known, including holds, adjustments, and retests when the beverage was out of specification.
- Final beverage classification documented
- Corrective action documented when result is out of range
- Product held or removed from service if out of specification
- Retest performed after adjustment when required
Review and Sign-Off
This section shows whether a supervisor, dietitian, or inspector reviewed the result and leaves an audit trail for unusual or failed tests.
- Supervisor or dietitian review completed when needed
- Supporting notes or observations recorded
- Photo evidence attached for unusual or failed result
- Inspector signature
How to use this template
- Enter the inspection date, time, location, intended beverage or recipe name, and target IDDSI level before you start the test.
- Prepare a representative sample, mix it uniformly, and confirm it is at the intended serving temperature before testing.
- Place the 10 mL syringe vertically, start the test with your thumb over the nozzle, and release the liquid for the full 10-second interval.
- Record the volume remaining in the syringe, convert that result to the measured IDDSI level, and compare it to the target level.
- If the result is out of range, document the corrective action, hold or remove the product from service, and retest after adjustment when required.
- Add review notes, attach photo evidence for unusual or failed results, and complete supervisor, dietitian, or inspector sign-off as needed.
Best practices
- Use the same syringe type and size for every test so results are comparable across shifts and locations.
- Test the sample at the temperature it will actually be served, not at a convenient prep-room temperature.
- Mix the beverage uniformly immediately before testing to reduce settling and separation errors.
- Treat borderline or unexpected results as a non-conformance until the product is retested and confirmed in range.
- Document the exact beverage name and recipe version so you can trace failures back to the correct formulation.
- Photograph unusual, failed, or disputed results at the time of testing so the record matches what was observed.
- Hold product that fails the target level instead of trying to correct the log after service has started.

Common use cases
Frequently asked questions
What does this IDDSI Liquid Flow Test Log cover?
This template records the 10 mL syringe flow test for beverages and thickened liquids, including the sample, serving temperature, measured volume remaining after 10 seconds, and the resulting IDDSI level. It also captures whether the result matches the intended target and whether the product was held, adjusted, or retested. Use it as the audit trail for each batch, recipe, or service run.
Who should complete this log?
It is typically completed by kitchen staff, dietary aides, or foodservice supervisors who prepare or verify thickened beverages. A dietitian or supervisor should review unusual, failed, or borderline results when your facility requires escalation. The person completing the test should be trained on the IDDSI flow test method and your local service procedures.
How often should the flow test be performed?
Use it whenever a beverage or thickened liquid is prepared, portioned, or changed in a way that could affect thickness, such as a new batch, recipe adjustment, temperature change, or product substitution. Many facilities also test at the start of service and after any hold time. The right cadence depends on your menu, production volume, and risk level.
Is this log only for hospitals and long-term care?
No. It fits any setting that serves IDDSI-modified drinks, including hospitals, skilled nursing, assisted living, rehabilitation, and some school or community feeding programs. It is especially useful wherever dysphagia risk makes consistency critical. If your operation does not serve thickened liquids, the template is not necessary.
What should I do if the result does not match the target level?
Document the out-of-range result, hold the product if needed, and correct the recipe, mixing method, or temperature before retesting. If the beverage cannot be brought into range, remove it from service and prepare a new batch. The log should show both the failure and the corrective action so the issue is traceable.
Why does serving temperature matter in this test?
Temperature can change how a thickener performs and how a drink flows through the syringe, so the sample should be tested at the intended serving temperature. A product that passes when cold may not pass when served warm, or vice versa. Recording temperature consistency helps explain borderline results and prevents false confidence.
Can this template be customized for different thickener brands or recipes?
Yes. You can add fields for thickener brand, recipe ratio, batch number, hold time, or beverage type if those details matter in your operation. The core log should still preserve the IDDSI test setup, the measured result, and the final classification. Customization is useful when multiple staff members prepare the same drink in different locations.
How does this compare with an ad hoc note or verbal check?
An ad hoc note often misses the exact test result, the target level, or the corrective action taken after a failed test. This log creates a repeatable record that supports consistency, handoffs, and review by supervisors or dietitians. It also makes it easier to spot recurring problems such as temperature drift or mixing errors.
