*Turnaround times are estimated from receipt of satisfactory specimen and test request form at the laboratory to release of clinical report. The turnaround time may vary depending on the nature of the specimen and the complexity of the investigation required. The above table is only a guideline and the complexity of a case and the requirement for further investigations may change this.

About Long QT Syndrome (LQTS)

Long QT syndrome (LQTS) is an inherited heart rhythm problem, characterised by QT prolongation and T wave abnormalities on an ECG that are associated with tachyarrhythmias, most typically the ventricular tachycardia torsade de pointes (TdP).

The prevalence of LQTS is estimated to be 1 in 2,500 and occurs across all ethnic groups.

Approximately 75% of LQTS cases are caused by pathogenic variants in one of 15 known genes, most frequently with autosomal dominant inheritance, though there are also recessive forms.
