Cytogenetics — NABL criteria
NABL 112A, section 7.10 — Technical Requirements, Discipline Wise
Checked against NABL 112A (Issue 01, 18-Dec-2024) · page updated 23 September 2026
These are the requirements NABL applies specifically to Cytogenetics, quoted from NABL 112A. They sit on top of the general requirements every accredited laboratory must meet, not instead of them.
What NABL 112A requires of this discipline
- For PGD, the laboratory shall not perform sex selection before implantation of embryonic cells.
- The laboratory shall follow all the rules and regulatory issues of the PCPNDT Act.
- Quality of reporting shall be used as determinant of competence.
- The maintenance schedule and protocol for the Cytogenetics cell culture laboratory shall be documented.
- The process for dealing with deviant samples shall be specified in procedure manuals for sample reception.
- Lesional and nonlesional skin shall be kept in separately marked containers | Sterile 50ml centrifuge tube or 1.
- A minimum of five metaphases shall be analysed and 2 karyogrammed.
- The guidelines to be followed in such cases shall be specified in the laboratory manual and shall be made available in the laboratory for easy reference.
- Fluorescent in Situ Hybridization (FISH) • Slides of interphase and metaphase FISH analysis shall be scored by two readers familiar with the expected signal pattern of the probe used.

HealthFlow is not NABL accredited and is not an accreditation body. Using it does not make a laboratory accredited or compliant. These pages describe what the standard requires; meeting it is the laboratory's own responsibility.
What the software contributes is evidence produced by normal work: turnaround time measured per test, reports versioned and locked on authorisation with dual signatures, every report access written to an append-only audit trail enforced at the database and retained two years, and full export whenever you want it.
