Sample Type Selector for PCR Workflow Planning
Use sample matrix, target nucleic acid, throughput, and automation preference to narrow the most practical extraction and workflow path.
Key takeaways
Sample type should be one of the first filters in PCR workflow planning because extraction method, inhibitor profile, and QC design all change with the matrix being tested.
- Sample matrix affects extraction, inhibitor handling, and workflow fit.
- Respiratory, blood, swab, and saliva samples can drive different process choices.
- The tool is intended to narrow workflow directions, not replace validation.

FAQ
Common questions
Does this tool choose a product?
No. It narrows workflow direction and comparison topics so users can move into extraction, QC, and product evaluation with better context.
Should sample type be the first planning filter?
Usually yes, because matrix characteristics often drive extraction, inhibitor handling, and workflow suitability early in the decision process.
What it is
The Sample Type Selector is a decision-support entry point that organizes workflow planning around the matrix being processed. It helps users identify likely extraction paths, workflow notes, and related comparison topics.
Why it matters
Sample type drives inhibitor risk, handling constraints, throughput assumptions, and compatibility checks. Starting with the matrix reduces avoidable rework in later evaluation stages.
Workflow and evaluation steps
1
Choose the sample type
Start with respiratory, blood, swab, saliva, or other matrix categories.
2
Set workflow assumptions
Define nucleic acid target, daily volume, and automation preference.
3
Review recommended paths
Use the output to move into extraction, throughput, and QC comparison pages.
Key comparison factors
- Sample Matrix
- The matrix shapes inhibitor profile and handling complexity.
- Target Nucleic Acid
- DNA and RNA workflows may impose different extraction and stability requirements.
- Automation Preference
- Automation constraints affect which extraction and workflow models are practical.
