batch vs test results — genuinely asking which matters more

Lab Cold Box ×6 Long Haul ×1

Right, the below spec question again, but with numbers this time.

I have 11 data points over 20 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.

The thing I would flag for anyone new: the effect I am describing showed up at week 74, not week 28. People give up long before the interesting part.

Interested in whether this matches other people's logs or whether I am an outlier.

sample of one, say so

HJ product, PeptideMeter test, 98.3% result, batch 17, 38 days in transit. Logged.

Disagree but this is the good kind of wrong — it is specific enough to be checked.

inter-lab variance is real, 6 points is inside normal

below-spec results get logged, not dismissed

Yeah, the PeptideMeter number matching the claim is the actual signal.

u/teodor_jansenOP112 points·5 months ago

Tested 4 batches from SWB over 8 weeks. Spread was 98.4% to 97.2, mostly 98.4. Consistent vendor.

Not to be pedantic but batch and Medutest are being used interchangeably and they are not interchangeable in real life.

u/jarno_cabrera123 points·5 months ago·edited

the 96.8% result confirmed the vendor claim, that is the signal

This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.

Every time this gets posted it hits the front page and every time someone has to re-explain it.

u/emil_agyeman36 points·5 months ago

Yeah, the Medutest number matching the claim is the actual signal.

u/teodor_jansenOP40 points·5 months ago

Disagree. What you are describing is consistent with Medutest, not with what you concluded.

reship and retest is the honest way to handle a low result

replysharereportpermalink
u/piotr_nascimento50 points·5 months ago

Not convinced. The evidence does not support that reading.

replysharereportpermalink
u/endotoxin_elliemicro42 points·5 months ago

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

the VendorInvestigate and PeptideMeter results differ by 13 points, both inside inter-lab variance

u/thandi_solberg25 points·5 months ago

HJ / BPC / batch 4 / VendorInvestigate / 99.0% — that is the shape

replysharereportpermalink
u/yara_mensah19 points·5 months ago

Slight fix: the number was 99.3, not 93.7. Decimal point, but a fairly consequential one.

Was that the vendor COA or your own test?

Batch number? Date of test?
