How to use the cell viability percentage calculator
Find the percent of live cells from live and dead cell counts, such as trypan blue counts. Enter live cells, dead cells in the fields above; the viability, dead fraction are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “cell viability”, “trypan blue viability”, “percent live cells”, “calculate cell viability percentage”, “find viability”.
Formula
Variables
- live — Live cells (cells)
- dead — Dead cells (cells)
Worked example
With live cells = 180 cells, dead cells = 20 cells, the calculator gives viability ≈ 90 %; dead fraction ≈ 10 %.
Frequently asked questions
What is the cell viability percentage calculator used for?
Find the percent of live cells from live and dead cell counts, such as trypan blue counts. It helps with questions such as “cell viability”, “trypan blue viability”, “percent live cells”.
What is the formula for the cell viability percentage calculation?
Viability (%) = live / (live+dead) × 100. Dead fraction (%) = 100-[Viability]. Here live is live cells (cells), dead is dead cells (cells).
What inputs do I need for the cell viability percentage calculator?
You need live cells in cells, dead cells in cells. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the cell viability percentage calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the cell viability percentage result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
