Overview
Toxicology Reflex Management automates confirmation workflows by dynamically adding reflex and prescription drugs into Confirmation based on billing configuration and device results.
What is Toxicology?
Toxicology is the study of harmful substances and their effects on the human body. In our system, toxicology primarily focuses on drug testing workflows.
These tests are used to identify whether specific drugs or substances are present in a patient sample such as blood or urine.
For example:
- A blood sample may be tested for multiple substances
- The result may indicate that the sample is positive for cocaine
- Based on this detection, additional confirmation workflows can be triggered
Toxicology testing is commonly used in:
- Workplace drug screening
- Clinical laboratories
- Compliance and rehabilitation programs
- Forensic investigations
Components in Toxicology
Toxicology workflows are divided into multiple components, each serving a specific purpose in the testing and confirmation process.
Screening
The Screening component is the initial stage of toxicology testing.
It identifies the primary drug groups or substances present in a sample. Screening tests are generally broad and designed for rapid detection.
Example:
- Detecting the presence of cocaine, opioids, or benzodiazepines in a urine sample.
Confirmation
The Confirmation component is used to validate screening results with higher accuracy.
These tests are more precise and help confirm the exact substance detected during screening.
Example:
- Confirming a positive benzodiazepine screening result using a targeted confirmation test.
Prescription
The Prescription component compares detected substances against the patient’s prescribed medications.
This helps laboratories and clinicians evaluate:
- Medication compliance
- Potential misuse
- Diversion or unauthorized substance usage
Other Components
Additional components may also exist depending on laboratory workflows, such as:
- History
- Summary
- Custom reporting sections
These components help provide better clinical context and reporting clarity.
Drugs in our LIMS
Drugs are configurable entities within the LIMS and form the foundation of Toxicology workflows.
Laboratories can create and manage drugs through the operations section of the application, allowing them to define the substances they want to test and track.
Default Drugs
Labs can configure a set of default drugs to streamline onboarding and testing workflows.
This allows laboratories to begin processing toxicology tests immediately without requiring manual setup for every workflow.
Panels
A Panel is a collection of related drugs grouped together for testing purposes.
Panels help laboratories:
- Organize testing workflows
- Perform bulk drug screening
- Simplify configuration and billing
Example:
- Drug Abuse Panel
- Opioid Panel
- Benzodiazepine Panel
Brands
A Brand represents a group of drugs associated with a particular pharmaceutical or medical category.
This grouping helps laboratories and clinicians:
- Understand medication classifications
- Perform medication-related analysis
- Support prescription and compliance workflows
These configurations make toxicology workflows more flexible, scalable, and easier to manage across different laboratory use cases.
Toxicology Reflex Management
Toxicology Reflex Management automates the addition of confirmation drugs based on screening results or prescription selections.
There are two types of reflex workflows supported in Toxicology:
- Screening Reflex
- Prescription Reflex
1. Screening Reflex
Screening Reflex is triggered based on the values received from the device during screening.
If a drug added in the Screening component exceeds its configured cutoff value, the system can automatically add one or more reflex drugs into the Confirmation component.
Example
Consider the following configuration:
- Drug: Ketamine
- Cutoff Value: 50
- Reflex Drugs:
- Noroxycodone
- Naltrexone
Workflow
- Ketamine is added during billing under the Screening component
- Device sends the Ketamine result
- System checks whether the received value exceeds the configured cutoff
- If the value is greater than
50:- Noroxycodone is added to Confirmation
- Naltrexone is added to Confirmation
Important Requirement
For this automation to work, the user must enable the:
- Screening Reflex setting
inside the Confirmation Component Reflex Configuration.
Without this setting enabled, reflex drugs will not be automatically added to the Confirmation component.
2. Prescription Reflex
Prescription Reflex works differently from Screening Reflex.
In this workflow, drugs added under the Prescription component during billing are automatically added to the Confirmation component without waiting for device results.
This reflex does not depend on:
- Device values
- Cutoff validation
- Screening detection
Workflow
- User adds drugs under the Prescription component during billing
- User enables:
- Prescription Reflex setting
- System automatically adds those prescription drugs into Confirmation
Why Prescription Reflex Exists
Prescription drugs are medications that the patient is already known to be taking.
Since these drugs are expected to appear during confirmation testing, laboratories can configure them to be automatically included in the Confirmation workflow.
This helps:
- Reduce manual effort
- Speed up confirmation workflows
- Improve operational efficiency
Summary
| Reflex Type | Triggered By | Requires Device Result | Uses Cutoff Value |
|---|---|---|---|
| Screening Reflex | Screening result | Yes | Yes |
| Prescription Reflex | Billing selection | No | No |
FAQs
1. What is the difference between Screening and Confirmation?
- Screening is the initial detection phase used to identify possible drugs or substances present in the sample.
- Confirmation is the validation phase used to accurately confirm the detected substances using more precise testing methods.
2. What is a cutoff value in Screening Reflex?
A cutoff value is the threshold used to determine whether a detected drug should trigger reflex actions.
If the device-received value exceeds the configured cutoff:
- The associated reflex drugs are automatically added to the Confirmation component.
Example:
- Ketamine cutoff =
50 - Device sends value =
65 - Reflex drugs are added to Confirmation
3. Does Screening Reflex work without device results?
No.
Screening Reflex depends on:
- Device-generated values
- Cutoff validation
Without a device result, the reflex workflow will not trigger.
4. Does Prescription Reflex require a cutoff value?
No.
Prescription Reflex is completely independent of:
- Device values
- Cutoff ranges
- Screening detection
It is triggered directly from billing selections.
5. Why are prescription drugs automatically added to Confirmation?
Prescription drugs are medications that the patient is already expected to be taking.
Since these substances are likely to appear during confirmation testing, the system allows them to be automatically included in the Confirmation workflow to reduce manual effort.
6. What happens if the Screening Reflex setting is disabled?
If the Screening Reflex setting is disabled:
- Reflex drugs will not be automatically added to Confirmation
- Even if the device value exceeds the configured cutoff
7. What happens if the Prescription Reflex setting is disabled?
If the Prescription Reflex setting is disabled:
- Prescription drugs added during billing will not be automatically added to Confirmation
8. Can a drug have multiple reflex drugs?
Yes.
A single drug can trigger multiple reflex drugs in the Confirmation component.
Example:
- Ketamine
- Noroxycodone
- Naltrexone
9. Can Screening Reflex and Prescription Reflex work together?
Yes.
Both reflex workflows can operate simultaneously:
- Screening Reflex handles device-triggered confirmation additions
- Prescription Reflex handles billing-triggered confirmation additions
10. Are Toxicology reflex workflows range-based like Pathology?
No.
Pathology reflex workflows are typically based on numeric parameter ranges.
Toxicology reflex workflows are primarily:
- Detection-driven
- Device-triggered
- Drug-focused
Although cutoff values are used in Screening Reflex, the workflow itself is centered around drug identification and confirmation.
