CBC:

External quality assessment: Participate in external quality assessment program ISHTM – AIIMS EQAS programme. Every 3 monthly EQAS is done for following equipments:

  1. Micros 60 (EQ-01) [Code no. 375- Jan, April, July and Oct cycle]
  2. Micros 60 (EQ-28) [Code no. 432- Jan, April, July and Oct cycle]
  3. Pentra Yumizen H500 (EQ-05) [Code no. 213- Jan, April, July and Oct cycle]
  4. Pentra XLR (EQ-08) [Code no.899- Jan, April, July and Oct cycle]

Data are maintained in C\Records\File\2\Results of EQA and interlaboratory comparison.

  • >

    Internal Quality Control:-Quality control samples are run on the cell counters Micros 60[EQ-49], Micros 60[EQ-28], Pentra Yumizen H500 (EQ-05). and Pentra XLR (EQ-08).

  • >

    Daily 2 levels QC samples are being run on hematology analyzers depending on the availability of QC samples. All the records are kept in file C\Records\File\9\Internal Quality Control Records. In case of unavailability of QC sample for any of the cell counter, inter-instrument comparison is done with cell counter on which QC sample is being run.

  • Inter Instrument comparison :

  • Daily one random patient sample is run for inter instrument comparison between MICROS 60[EQ- 49] with MICROS 60[EQ-01], Pentra Yumizen H500 (EQ-05) with MICROS 60[EQ- 49], Pentra XLR (EQ-08) with MICROS 60[EQ-28], MICROS 60[EQ-28] with MICROS 60[EQ- 49]. Records of comparative data are maintained in C\Records\File\9\Inter-instrument comparison.
  • Precision check done for Micros 60[HI/EQ- 49,28, 01], Horiba Yumizen H500[EQ-05] & Pentra XLR [EQ-08] once in 6 months.
  • Linearity check done for MICROS 60[EQ- 49,28,01], Horiba Yumizen H 500[EQ-05] & Pentra XLR [EQ-08] once in 6 months.
  • Check for carry over of sample is done for Micros 60[HI/EQ-49,28,01], Horiba Yumizen H500[EQ-05] & Pentra XLR [EQ-08] once in 6 months.
ESR:
  • Daily compare the 1 random sample results on automated analyzer with manual method and records of comparison are filed in C\records\file\9\Internal quality control records -G
  • Daily one random patient sample run in duplicate in evening batch on Automated ESR analyzer and records of comparison are filed in C\records\file\9\Internal quality control records -G.
  • Monthly one sample is send for interlaboratory comparison and records of which are filed in C\Records\file2\Results of EQA and interlaboratory comparison

RC:

  1. External Quality assessment: Participate in External Quality Assessment Program [ISHTM- AIIMS EQAP PROGRAMME ]- EQAS done 4 cycles in a year and maintain data in C\Records\File\2\Results of EQA and interlaboratory comparison
  2. Internal Quality Control: Weekly one random RC sample is checked internally by three different observers and records of comparison are kept in file C\Records\File\9\Records of internal quality control records.

PSCM:

External quality assessment: Participate in external quality assessment program [ISHTM- AIIMS EQAP PROGRAMME] - EQAS done 4 cycles in a year and maintain data in C\Records\File\2\Results of EQA and interlaboratory comparison

Internal Quality Control: Weekly one random PSCM slide is checked internally by three different observer and records of comparison are kept in file C\Records\File\9\Records of internal quality control records.

PSMP:

  • Internal Quality Control: Weekly one random PSMP slide is checked internally by three different observer and records of comparison are kept in control C\Records\File\9\Records of internal quality control records.
  • External quality control: Monthly one random sample for malaria examination is sent to Metropolis (NABL Accredited Lab) and records of comparison are kept in C\Records\File\2\Results of EQA and interlaboratory comparison.
  • Every PSMP is crosschecked daily.

PT, APTT:

  1. Control plasma (Freeze dried pooled plasma of 20 normal individual) is run in duplicate as normal control with every batch and mean is derived and recorded. Done with every lot change.
  2. Daily level 2 controls run. Results of control samples are recorded in C\Records\File\9\Internal Quality Control Records
  3. External quality assessment:
  1. Participate in external quality assessment program ( ISHTM-CMC VELLORE EQAS PROGRAM- HAEMOSTASIS )[ Pin no 1386- March, July and Nov cycle] every 4 monthly and maintain data in C\Records\file2\Results of EQA and interlaboratory comparison
  1. Inter instrument comparison is done once a day by running a pooled normal plasma on Elite Pro coagulation analyzer and then by Manual method. Results are compared and documented.

  2. OR

  3. Inter instrument comparison is done once a day by running a random sample on Elite Pro & STAGO fully automated auto analysers, and then by Manual method. Results are compared and documented.

  4. Precision check on Elite Pro & STAGO coagulation analyzer once in 6 months.

Bone marrow Aspiration:

  • All the bone marrow aspiration cases are reported by a panel of three pathologists
  • Inter laboratory comparison is done once in every 6 month with NABL accredited laboratory (Metropolis lab)
  • Internal Quality Control between 2 observer is done three monthly and records of which are kept in HI:C\Records\file\9\internal quality control records M

Malaria antigen, plasmodium vivax & falciparum

The test cards have an internal positive control band labeled as “C”. This band must show positivity with each run.

Monthly minimum one malaria smear is cross checked with test card for malaria antigen and results are recorded in C\Records\File\9\Internal Quality Control Records
