Coming back to: Lateral-flow and colorimetric approaches: the specificity problem Replied, post #60 · Analytics › Home & field testing · 28 Jun 2026 · 4 likes Sample handling matters: if a sample is contaminated or degraded before testing, the test gives you the result for the degraded sample, not for fresh material. That is…
An 18-month record including the parts that went badly Replied, post #30 · Outcomes › Progress reports · 1 Jun 2026 · 8 likes Picking up post #27: that is the part I would want checked first. Plateaus and resets: if weight loss stalls and then resumes, that is ordinary. It is not evidence that…
