ABOUT CMC-EQAS
:
The attainment of quality service in a
laboratory requires a comprehensive Quality Assurance Program which includes
both Internal and External quality control material.
The Department of Clinical Biochemistry, Christian Medical College, Vellore under the
banner of The Association of Clinical Biochemists of India (ACBI) is conducting
an External Quality Assessment Scheme (EQAS) since 1978. The Participants
represents all the states of India and also Andaman and Nepal. The participating
laboratories include teaching and non-teaching hospital laboratories, government
as well as private, small hospitals, private clinics and diagnostic centers.
It is a twelve month program starting from January to December every year. Those
who wish to enroll their laboratories during the middle of a cycle can do so by
paying the same registration fee, but those labs who report results for at least
six months alone are eligible for the participation certificates at the end of
the cycle.
The various programs in the scheme includes
1.Chemistry I - Glucose, Urea,Ccreatinine,T.Bilirubin, T.Protein, Albumin, Calcium,
Pphosphorus, Uric acid , T.Cholesterol, Triglyceride, HDL cholesterol, Sodium,
Potassium, Chloride, Bicarbonate, AST, ALT, ALP, amylase,
Iron and Magnesium.
*Lithium and UIBC* (Non accredited)
2. Chemistry II – Glucose, Urea, Creatinine, T.Bilirubin, T protein, Alumin, Uric acid, Cholesterol and Triglyceride.
3.Thyroid and Cortisol – Total T4, Free T4, TSH,Total T3 and Cortisol.
4. HbA1c.
5. Reproductive Hormones – LH, FSH, Prolactin, Testosterone, beta HCG, Estradiol and
Progesterone.
6. Biochemical Markers for Down’s screening – Alpha Fetoprotein, PAPPA and Free beta
HCG.
7.Urine Chemistry – Urea, Creatinine, Calcium, Phosphorus, Uric acid, Sodium and Potassium.
8.Tumor Markers – AFP, BHCG and PSA(Total).
9. Urine (Microalbumin & Protein) - Microalbumin and Protein.
10. Trace Metals* - Copper and Zinc(Non accredited).
11. Cardiac Markers* - Troponin T, CK-MB Mass and Creatine KInase(Non accredited).
The PT material is prepared from pooled plasma / whole blood (for A1c) negative for viral checks and obtained from blood bank of the institution.
Pt material for Urine Chemistry is prepared from healthy voluntary donors from the laboratory.
The basic operation involves preparation
of a master pool of human serum as per WHO recommended procedure, dispensing the
correct volume into the vials and lyophilization. Homogeneity
and stability checks are done as per the ISO 13528:2015 standards. The
lyophilysed vials are sealed, well packed in thick envelops and distributed
through courier service or postal service to all the participating laboratories.
Dispatch of samples is done once in four months, during the 3 of April, August and December. The laboratories are requested to reconstitute
the correct sample, analyse and enter the results in the web site before the 20th
of every month. Any amendments can be made only till the 25th of the
month and it should be sent through an e mail only clearly mentioning the lab
number and reason for amendment. Once the report is published on the net, no
amendment can be made. Evaluation of the report is based on WHO and ISO
13528:2015 recommend expressions such as Robust mean for the assigned value and
SDI (Z score) for individual parameters.
Details on monthly report and the statistical tools are available on the monthly
summary page. Evaluated monthly report is uploaded into the net by 1st Week of the succeeding month.
Each laboratory is assigned a lab number
and they are requested to secure the pass word.
The participants are
requested not to share or discuss their results with other laboratories before
the release of report on to the web site.
After the completion of the
cycle the yearly summary is updated into the web site for individual labs and
certificates are sent to the eligible laboratories.
The CMC-EQAS providers
maintain confidentiality of the participants’ demographics, results, reports or
any other information provided by them.
This scheme is fully run by the
department of Clinical Biochemistry and none of the components are sub
contracted.
The EQA program has created
awareness among participants and proved to be a valuable exercise and the
numbers of laboratories are steadily increasing every year.
The Chemistry, Thyroid Hormones, Reproductive hormones, HbA1c & Biochemical Markers for Downs screening programmes are accredited by NABL in accordance
with the standard ISO/IEC 17043:2010 The participants are requested
to contact us for any queries.
