The liver toxin that closes beaches. Order it when you know Microcystis is what you have.
Checkout arrives with the store connection. Orders attach to the lake on your account.
Not sure which toxin to test for? Start with the Rapid Bloom ID & Cell Count. Twenty-four hours and one sample identifies the organisms in your bloom, which tells you which toxin is plausible. Reach for a targeted toxin test once you know what you are dealing with — or when you already do.
Microcystin is the most common cyanotoxin in North American fresh water and the one most state advisory thresholds are written around. It is a liver toxin, produced by Microcystis and several other genera, and it is the toxin that closes beaches.
Screening uses ADDA-ELISA, an immunoassay that responds to over a hundred known microcystin congeners as a single total.
Screening is by ELISA, the method behind most state recreational advisory programmes. Sensitive, fast, and appropriate for a swim-or-no-swim decision. It is not congener-specific — it reports a total, not a breakdown. Ask the Boathouse about LC-MS/MS confirmation if you need congener detail or a regulatory-grade result.
Cyanobacteria produce more toxins than these three. Cylindrospermopsin, nodularin, guanitoxin, lyngbyatoxin, BMAA and others can all appear in fresh water. If you need a toxin not listed in the Toolbox, contact Lake Pulse and we will arrange it.

Results from this product land in your lake's shared record in the Portal — next to everything else your lake has ever measured, instead of in an inbox.
Compare subscriptionsEvery result shows the date and time the sample was collected. Results reflect one sample, collected at a specific place and depth, and analyzed by an independent accredited laboratory using the method listed on this page. Lake conditions change across a lake and over time, sometimes within hours, in ways a single sample may not capture. Every method has detection and reporting limits; where the laboratory provides them, they are reported with your results. A detection is not a diagnosis, and a non-detection does not prove absence. Results are not a regulatory or compliance determination unless the agency involved accepts them as one. Lake Pulse reports measurements; it does not determine whether water is safe for swimming, drinking, pets, or recreation. Always follow posted signs and your state or local health advisories. Recommendations are options to consider; decisions, and responsibility for any action taken, rest with you.
Blooms move, and toxin production can change quickly. A low or non-detected result applies only to the water sampled. The absence of a detected bloom or toxin does not mean the water is safe.
Our team can help you choose the right solution for your lake, explain how results sync to your Portal, or point you to the right subscription.
