An oral fluid drug test kit is a single-use consumable onto which a saliva sample is applied, carrying test zones that correspond to substance groups. It is also called a saliva drug test kit or drug screening cassette; in the ARMAS range it is the UTK. The kit is used together with a drug testing device that reads the result and records it.
This article explains how the kit works, how an oral fluid sample is collected, why kit and reader are used together, and what institutions consider when planning consumable supply. Our drug testing devices guide covers the complete system and complements this article.
What Is a Drug Test Kit and How Does It Work?
The kit consists of a carrier with test zones and a structure that delivers the sample to those zones. When oral fluid is applied, the test zones react; each zone corresponds to one substance group covered by the kit. The reaction is read and evaluated optically by the drug testing device.
The kit is single-use. A new kit is opened for every test and the used kit is disposed of according to the organisation's consumables procedure. The substance groups a kit screens for, its screening panel, are configured by model and by the customer's requirement. Current panel information is given on the product page and in the technical documentation.
Why an Oral Fluid Kit?
Kits used in institutional screening are oral fluid based. The sample is collected under the operator's observation without a private area, which is a decisive convenience at roadside checkpoints, workplace gates and mobile control points where many people are screened in a short time. The ARMAS UTK belongs to this class.
The essential difference between retail self-test kits and the kits used in institutional screening lies in how the result is read and documented. Retail kits are read by eye and keep no record. In an institutional system the kit is read by a device, and the result is recorded with date and time and reported.
How an Oral Fluid Sample Is Collected
Depending on the kit model, oral fluid is collected in one of two ways:
- With the pad integrated into the kit: the collection pad is part of the kit. The sample is taken with the pad and the kit goes straight into the device. Because no further handling is needed, this suits single-operator checkpoints.
- With an external collection unit: the sample is taken with a separate collection pad. An indicator on the pad changes colour when enough sample has been collected. The sample is transferred to a dropper and applied to the kit's test zones. This separates collection from reading, which helps when many people are screened in succession.
In both methods the kit carries control lines that show the sample has been applied correctly. A kit with no control line is invalid and the test is repeated with a new kit.
Why Kit and Device Are Used Together
The reaction on a kit can be observed by eye. Institutional screening, however, requires a result that is read independently of the operator and can be reviewed later. The drug testing device provides this:
- Kit identification: through the identification tag on the kit, the device reads the kit's panel configuration, lot and serial information, expiry date and whether it has been used before. Expired or used kits are rejected.
- Locking: analysis does not start until the kit is fully seated in the device, which secures the reading in vehicles and other moving environments.
- Automatic evaluation: the device manages the analysis time itself and displays the result; the operator does not interpret anything.
- Recording: the result is written to the device memory with date and time. Details of the tested person and the operator can be added and a printout produced.
Device functions and the other system components are described in our drug testing devices article. For product details see the UTC drug tester page.
Storage, Expiry and Lot Tracking
Because the kit is a consumable, stock management matters as much as device management:
- Storage conditions: kits are stored unopened under the conditions specified by the manufacturer. Seasonal temperature swings must be considered for kits kept in vehicles.
- Expiry date: printed on every kit. On tagged kits the device checks the date itself.
- Lot tracking: recording the lot number of the kit used allows any later enquiry to trace which batch was involved.
- Supply planning: annual test volume is estimated to size kit requirements, and kit supply continuity is secured as part of the device purchase.
Where Oral Fluid Drug Test Kits Are Used
Together with the drug testing device, oral fluid kits are used in:
- Roadside enforcement: screening drivers at checkpoints. The procedure is described in roadside drug testing.
- Workplace screening: shift entry or for-cause checks at construction sites, mines, manufacturing plants and logistics operations.
- Fleet operations: pre-trip driver checks.
- Healthcare and security units: rapid preliminary assessment and entry controls.
What to Consider When Buying Drug Test Kits
In institutional procurement the kit is assessed together with the device it will be read on and the screening process it will serve:
- Device compatibility: the kit must be recognised and read by the device in use.
- Panel configuration: coverage of the substance groups relevant to the organisation's purpose, agreed with the manufacturer.
- Collection method: integrated pad for single-operator, low-volume points; external collection unit for high throughput.
- Certification: CE marking and available technical documentation.
- Supply continuity: guaranteed kit availability for the device's service life. Direct supply from the manufacturer is an advantage here.
- Operator training: standardised instruction in sample collection and kit handling.
The ARMAS UTK Drug Test Kit
ARMAS Elektronik designs and manufactures both the drug test kit and the UTC device that reads it in Türkiye. The UTK drug test kit is a single-use oral fluid kit available with an integrated pad or an external collection unit, and with an optional identification tag that lets the device recognise it automatically. Because kit and device come from the same manufacturer, the panel can be configured for each customer and kit supply is secured directly by the producer.

Frequently Asked Questions
Is an oral fluid drug test kit the same as a saliva drug test kit?
Yes. Oral fluid kit, saliva kit and screening cassette all describe the same single-use consumable onto which the sample is applied. In the ARMAS range this is the UTK.
How many times can a drug test kit be used?
Once. A new kit is opened for every test. On tagged kits the device will not start a test with a kit that has already been used.
Which substances does the kit screen for?
The substance groups covered, the screening panel, are configured by model and by the customer's requirement. Refer to the technical documentation on the product page or contact us for current panel information.
Is a result from the kit definitive?
No. Kit and device deliver a screening result. Positive results are expected to be confirmed before any sanction is applied.
How should kits be stored?
Unopened, under the conditions specified by the manufacturer, with expiry dates tracked. Seasonal temperature differences should be considered for kits kept in vehicles.
How is kit supply planned for institutional purchases?
Annual test volume is estimated to determine kit requirements, and supply continuity is secured together with the device purchase. As the manufacturer we can plan this with you.
