[Lab] MKM cagri — Medutest came back 97.2% against a claimed 97.0%

Labbranch of 6 comments

The claim in the title is exactly the claim I am making: MKM cagri — Medutest came back 97.2% against a claimed 97.0%. Nothing implied beyond it. Since the title puts numbers in the shop window: 97.2% and 97.0%. System suitability — repeat injections, tailing factor, plate count, RSD on area — is what tells you the…

About c/hplc

The analytical deep end: RP-HPLC methods, gradient design, integration decisions, LC-MS confirmation, amino-acid analysis, water content, and why two labs can report 98.1% and 96.4% on the same vial and both be right. Post the chromatogram, not the summary line.

c/hplc rules
  1. Chromatogram or it did not happen. Axis labels included.
  2. State the method: column, gradient, detection wavelength, injection volume.
  3. Area% is not mass%. Posts that conflate them get a correction flair, not a removal.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
