[ANALYSIS-LAB-FIN-02] CALIBRATION IN PHARMACEUTICAL ANALYSIS

THIS FLASHCARDS IS ABOUT [ANALYSIS] CALIBRATION.

Non-negotiable

Precise dosing is?

Precision and Accuracy

In calibration there is a need for (2)?

Calibration

This is the set of operations that establish, under specified conditions, the relationship between values indicated by a measuring instrument and the corresponding values of a certified reference standard.

Yearly

(Ma’am Mel’s not sure")

Calibration is done?

Info

Instruments are calibrated constantly to certify that they are in their corresponding values.

Legal and Scientific Proof

Calibration is the “__________” that your lab results are true.

Cure and a toxin

A slight error in a drug’s concentration can be the difference between a?

• Good Manufacturing Practice (GMP)

• United States Pharmacopeia (USP)

Calibration is governed by strict regulatory frameworks like (2)?

• Patient Safety

• Regulatory Compliance

• Data Integrity

What are the (3) Importance of Calibration?

Hint: Pa-Re-Da

Patient Safety

Importance of Calibration:

Drugs have a narrow therapeutic window. Inaccurate measurements can lead to under-potency (ineffective medicine) or over-potency (toxic levels).

• Under-potency (ineffective medicine)

• Over-potency (toxic levels)

In Patient Safety, inaccurate measurements can lead to (2)?

Regulatory Compliance

Importance of Calibration:

Agencies like the Food and Drug Administration (FDA) and European Medicines Agency (EMA) mandate calibration under cMGP.

Current Good Manufacturing Practice (cGMP)

The FDA and EMA mandate calibration under?

Adulterated or Falsified

In Regulatory Compliance, if an instrument isn’t calibrated, the data it produces is legally considered?

Data Integrity

Importance of Calibration:

Calibration provides traceability. It ensures that a test result in one lab is identical to a result in any other lab worldwide, making the data “defensible” during audits or lawsuits.

Traceability

In Data Integrity, what key quality does calibration provide to ensure that test results are consistent across different laboratories worldwide?

It makes the data defensible

In Data Integrity, why is calibration important in audits or legal situations involving laboratory data?

• Batch Rejection

• Product Recalls

• Legal Action

What are the (3) Consequences of Failure?

Hint: Ba-Pro-Le

Batch Rejection

Consequence of Failure:

If an instrument is found to be out of calibration, every batch tested since the last “good” check must be investigated.

Product Recalls

Consequence of Failure:

If a miscalibrated device allowed a substandard drug onto the market, a recall is required, costing millions and damaging brand trust.

Legal Action

Consequence of Failure:

Failure to maintain calibration can lead to Warning Letters (Form 483), fines, or the total shutdown of manufacturing facilities.

• Warning Letters (Form 483)

• Fines

• Total shutdown of manufacturing facilities

In Legal Action, what are the (3) possible regulatory consequences of failing to maintain proper calibration in a manufacturing facility?

Hint: War-Fin-To

Form 483

This is a document issued when there are observed deficiencies, such as failure to properly maintain calibration, during an inspection.

• High Performance Liquid Chromatography (HPLC) / Gas Chromatography (GC)

What is the common standard used in HPLC/GC?

• Mass accuracy

• Linearity

• Repeatability

What is Calibrated in Analytical Balance?

Hint: MIR

NIST-traceable E2 class weights

What is the common standard used in Analytical Balance?

Slope and offset

What is Calibrated in pH Meter?

Certified Buffer Solutions (pH 4.01, 7.00, 10.01)

What is the common standard used in pH Meter?

• Wavelength accuracy

• Absorbance

What is Calibrated in UV-Vis Spectrometry?

• Holmium oxide glass or

• Potassium dichromate

What are the (2) common standards used in UV-Vis Spectrometry?

• Shaft speed (RPM)

• Temperature

• Wobble

What is Calibrated in Dissolution Tester (3)?

Hint: Sha-Te-Wob

Certified tachometers and thermometers

What are the (2) common standards used in Dissolution Tester?

Paper Trail

Regulatory Standards (USP & FDA):

The FDA and other bodies (like the EMA) demand a “__________” for every measurement.

USP <41> and <1251>

Regulatory Standards (USP & FDA):

These specific chapters of USP outlines the rigorous requirements for balances and weighing.

Traceability

Regulatory Standards (USP & FDA):

Every standard used in your lab must be traceable back to a national body (like NIST).

Birth Certificate

In traceability, if you use a weight to calibrate a scale, the weight must have its own “__________” showing it was calibrated by a higher-level lab.

21 Code of Federal Regulations (CFR) Part 11

Regulatory Standards (USP & FDA):

If your calibration data is stored digitally, it must have an audit trail (you can’t just delete a “failed” calibration result).

Audit Trail

In 21 CFR Part 11, if the calibration is stored digitally, it must have an?

Just read this scenario brah — Ma’am Mel

The “Out of Calibration” (OOC) Nightmare:

If an instrument is found to be out of calibration during a routine check, it triggers and Impact Assessment. You must go back and investigate every sample tested on that machine since its last successful calibration.

Example: If a balance fails its monthly check, every batch of medicine weighed on it for the last 30 days is now legally suspect and may require a recall.

• Frequency

• Tolerance vs. Action Limit

• Documentation

What are the (3) Different Areas for Calibration:

Hint: FTD

Frequency

Area of Calibration:

Calibrations aren’t just “once a year”. They happen at set intervals (monthly/quarterly) and also after major repairs or if the instrument is moved.

Tolerance vs. Action Limit

Area of Calibration:

Labs often set an “Action Limit” that is tighter than the “Legal Tolerance”. If the machine gets close to failing, you fix it before it actually breaks the rules.

Documentation

Area of Calibration:

“If it isn’t written down, it didn’t happen.”

A calibration sticker on the machine is not enough; a full report with raw data is required.
