Thank you sir for such a nice lecture

[@alvinjayan187]

Watched video again today. Really informative

[@Infiniteanalyst]

Glad you liked it!

[@omargomez5473]

tyvm for your clear explanation

[@chandanrastogi4065]

Great effort in simple manner.. thanks you sir.

[@Infiniteanalyst]

Thanks

[@ahmahbubalam569]

Thank you for this important video. I have gone through other similar videos too. Now, I am confused whether we have to use ‘standard error’ (generated by excel) directly imagining as same as ‘standard deviation’ or we have to convert generated ‘standard error’ into ‘standard deviation’ by multiplication with square root of number of paired measurements used first. I would appreciate if anybody clarifies the above. Thanks.

[@MondaynewmanYakubu]

The best explanation on how to calculate LOD and LOQ I have ever seen. What if your x-axis is a logarithm value (Logx) what further calculation may you do to obtain x

[@cristiangutierrez-reyes8644]

Exelente, muchas gracias

[@Infiniteanalyst]

Thanks

[@PiggyBOSS]

this tutorial video helped me a lot. thank you so much.

[@Infiniteanalyst]

Glad to hear that feedback

[@mmtbrr]

Perfect video thank you so much.

[@Infiniteanalyst]

Thanks

[@krishnakumarsarabu8004]

good informative video

[@mojika8447]

very helpful thank for sharing this video

[@Infiniteanalyst]

Glad to see that video was helpful.. Don't forget to share the video with your friends. It may help them too

[@Infiniteanalyst]

Thanks

[@Avani_Aadi]

Simple yet lucid illustration. Great work.

[@kltoumbouizgma2623]

Thank you 💞💞

[@lakshmipriyaridevi1033]

This video is very helpful but I would like to know why standard error value is used for standard deviation. Kindly clarify.

[@thirumurugant7487]

Nice work.
Thank you for your explanation

[@Infiniteanalyst]

You are welcome

[@thirumurugant7487]

Can you share me your papers about different methods of LOD and LOQ calculation.

EXCELLENT DEMONSTRATION

[@Infiniteanalyst]

Thanks .. don't forget to share with your friends

[@Infiniteanalyst]

Thanks

[@thecasualfront7432]

good stuff

[@ebrahimazadniya6127]

Thanks for video. Why did you use standard error instead of standard deviation for LOD and LOQ calculation?

[@p.j.882]

Can you use Microsoft example of linear regression?

[@chakertlili7385]

Thanks, could you help for LoD determination from log(concentration)

[@waseelaashraf3812]

Sir very much clear elaboration, can I use the same method for finding lod of my competitive ELISA results???

[@punchymuffin6402]

Hello shouldn't we be converting all standard error values to standard deviation by multiplying by the square root of 5?

[@xin61593]

Hi, thank you very much for the demo! I am just confused about the following:
ICH mentioned using standard DEVIATION for calculating LOD and LOQ, but the LINEST function gives standard ERROR right? Why do we not have to convert the SE value to SD value by multiplying with sqrt(n)?

[@mendozamunoznestor7546]

It must be converted to SD

[@william85028]

Hello, first thanks you for this presentation. Really a great work.
At the end you have 2 different results by using Y intercept SD or Residual SD of regression. So which one is the correct answer for the LOD and LOQ values ?

[@Infiniteanalyst]

Thanks for watching the video and query. Yes. Two different values are possible. Both are correct. That's why ICH given the options.. I will post a new video to show the reason for two values soon. Share with me your email address , I can share my papers, where I recorded Detection limits based on all five methods

[@Saadagi187]

@@Infiniteanalyst Hi sir, could you share me the papers on [e-mail] ?

[@nassimalijani8269]

This was my question too.

[@williambelr]

I want to calculate LOD and LOQ in UV-Vis spectrometry, I would like to know when to use SD of Y intercept over Residual SD of regression.
Thank you.

[@Infiniteanalyst]

Hi thanks for watching the video and query. ICH has given five options. End user can decide based on their requirements.

[@tizianodigiulio3534]

Thank you! I have 2 different results by using Y intercept SD or Residual SD of regression. What is the correct?

[@Infiniteanalyst]

Both are correct

[@kanikasharma2290]

Sir, if I have peak current instead of area in y-axis then shall I go with same procedure or I should find the area of the current curve and then proceed with regression fitting?

[@Infiniteanalyst]

You can go ahead with peak current. Y axis only a number, it can be any number

[@haliqferdian2475]

Hello.. i have the same case as your example above.. which one of LOD I can use?.. can i use from STEYX?.. I am sorry my english is not really good and maybe i missed some explanation..

[@Infiniteanalyst]

Ich is allowing you to use five methods for calculating LOD and LOQ. You can choose the one as per your convenience

[@udaymannelli1086]

Sir lostly find lod based on concentration.

[@simranjeet9602]

Sir why you used standard error instead of standard deviation?
Is it correct?

[@Infiniteanalyst]

You can use way for standard deviation

[@zulhelmi6285]

hello can I get the lod and loq files for learning purposes

[@Infiniteanalyst]

You can make to our own excel sheet. Watch the video once again . Each step explained in the video
