One of the earliest decisions an organisation faces when establishing a drug and alcohol testing program is whether to conduct testing in-house or to engage a third-party provider. Both approaches are legitimate, and neither is universally superior. The right choice depends on your organisation’s size, risk profile, geographic spread, internal capability, and budget.

This article provides a detailed comparison of the costs and capabilities of each model, along with a decision framework to help you determine the best approach for your specific circumstances.

In-House Testing: Cost Breakdown

Conducting testing in-house means that your own employees — trained and accredited as workplace testers — perform screening tests on your premises using your equipment. The costs associated with this model are as follows:

Training and Accreditation

• Initial training — accredited tester training courses typically cost between $500 and $1,500 per person, depending on the provider and the testing methods covered (urine, oral fluid, breath alcohol).
• Refresher training — testers must maintain their competency through periodic refresher training, typically every one to two years, at a cost of $300 to $800 per person.
• Number of testers — you will need enough trained testers to cover leave, shift patterns, and multiple sites. Most organisations require a minimum of two to three trained testers, and larger or multi-site organisations may require significantly more.

Equipment and Consumables

• Screening devices — oral fluid screening devices typically cost between $15 and $30 per unit. Urine screening cups range from $10 to $25 per unit. These are single-use consumables.
• Breath testing equipment — calibrated breath alcohol testing devices cost between $1,500 and $5,000, with annual calibration costs of $200 to $500.
• Collection supplies — chain of custody kits, specimen bags, temperature strips, gloves, and other supplies. These are modest per-test costs but aggregate over time.
• Storage — secure, temperature-appropriate storage for specimens awaiting transport to the laboratory.

Laboratory Costs

• Confirmatory testing — non-negative screening results require laboratory confirmation by a NATA-accredited laboratory. The cost per confirmatory test typically ranges from $80 to $200, depending on the substances tested and the laboratory.
• Courier and transport — specimens must be transported to the laboratory under chain of custody conditions. Courier costs vary by location and urgency.

Staff Time

• Testing time — each test takes approximately 15 to 30 minutes of the tester’s time, including preparation, collection, screening, and documentation.
• Administration — selection administration, record-keeping, reporting, and compliance management. This is often the largest hidden cost of in-house testing.

Outsourced Testing: Cost Breakdown

Engaging a third-party provider means that the provider’s testers attend your workplace to conduct testing. The costs are structured differently:

Per-Test Fees

• Standard testing — providers typically charge between $60 and $150 per test, depending on the testing method, location, and volume. This fee generally includes the screening device, collection, chain of custody documentation, and result reporting.
• Confirmatory testing — may be included in the per-test fee or charged separately, typically at $80 to $200 per non-negative specimen.

Additional Charges

• Callout fees — for out-of-hours, remote location, or urgent callouts, additional fees of $100 to $500 or more may apply.
• Travel costs — for regional or remote sites, travel time and costs may be charged separately.
• Minimum charges — some providers impose minimum charges per visit, regardless of the number of tests conducted.

What Is Included

The per-test fee typically covers the provider’s training, accreditation, equipment, consumables, and insurance costs. These are the provider’s overhead, amortised across their entire client base, which is why per-test pricing can be competitive even though the headline rate may seem higher than the marginal cost of an in-house test.

Capability Comparison

Cost is only one dimension of the decision. Capability is equally important, and the two models differ significantly in what they require from your organisation.

In-House Capability Requirements

• Internal expertise — you need at least one person with deep knowledge of testing procedures, Australian Standards, chain of custody requirements, and the legal framework. This expertise must be maintained as personnel change.
• Training management — you are responsible for ensuring that all testers are trained, accredited, and current. Lapsed qualifications compromise every test conducted by that tester.
• Equipment management — breath testing devices must be calibrated regularly. Screening devices must be stored correctly and used before their expiry date. Failure in either area can invalidate results.
• Quality assurance — you are responsible for monitoring the quality of your testing processes, identifying and correcting errors, and maintaining compliance with Australian Standards.

Outsourced Capability

• Provider’s responsibility — the provider is responsible for the training, accreditation, equipment, quality assurance, and compliance of its testers. These obligations are contractual and backed by the provider’s professional indemnity insurance.
• Reduced internal burden — outsourcing eliminates the need for internal testing expertise, training management, and equipment maintenance.
• Scalability — a provider can increase testing capacity at short notice (for post-incident callouts or blanket testing events) without the employer needing to train additional testers.

Hybrid Models

Many organisations adopt a hybrid approach that combines elements of both models:

• In-house random testing, outsourced for-cause and post-incident — routine random testing is conducted by trained internal testers, while time-critical for-cause and post-incident testing is handled by a provider who can respond at short notice.
• In-house at primary sites, outsourced at remote sites — organisations with a mix of large and small sites may find it cost-effective to test in-house at their largest sites while outsourcing at smaller or more remote locations.
• In-house screening, outsourced confirmation — the organisation conducts point-of-collection screening in-house and uses a provider only for confirmatory laboratory testing. This is the most common hybrid arrangement.

Decision Framework

The following framework can help determine which model — or which hybrid — is most appropriate for your organisation:

In-House Testing May Be Preferable When:

• Your organisation has a high testing volume (reducing the per-test cost of amortised overheads).
• You operate primarily from one or a small number of large sites.
• You have personnel with the aptitude and availability to be trained as testers.
• Rapid on-site testing capability is operationally important (for example, pre-start testing in mining or construction).
• You are prepared to invest in the ongoing training, equipment, and quality assurance that in-house testing requires.

Outsourced Testing May Be Preferable When:

• Your testing volume is low to moderate, making the fixed costs of in-house testing disproportionate.
• You operate across many sites, particularly in regional or remote areas.
• You do not have personnel available to be dedicated testers.
• You want to minimise the internal administrative and compliance burden.
• You require rapid access to testing capability that exceeds your internal capacity (for example, post-incident blanket testing).

The Role of Technology in Both Models

Regardless of whether testing is conducted in-house, outsourced, or hybrid, the management of the testing program — selections, record-keeping, chain of custody documentation, and reporting — benefits from purpose-built software. Technology does not replace the testing itself, but it transforms the administration, compliance, and governance of the program.

Whether you test in-house, outsource, or use a hybrid model, you need a platform to manage it all. Start a free trial of FairTest and centralise your testing program management — selections, records, chain of custody, and reporting — in one secure, auditable system.
