One sample, drawn at first light, processed before noon
Pulse Path Lab Core was established in 2017 by Dr. Miriam Calloway, a clinical biochemist who had spent the previous decade working in hospital laboratory medicine, most recently as deputy head of pathology at a regional teaching hospital. The decision to open an independent facility came after a period of watching turnaround times stretch and quality controls loosen under institutional budget pressure. The founding principle was straightforward: run fewer tests, run them correctly, and report them honestly. The first laboratory occupied a single-floor unit with two analysers, a biosafety cabinet, and a staff of four.
The turning point came in the autumn of 2019, when Pulse Path Lab Core entered a formal research partnership with a university pharmacology department to support a Phase II clinical trial. That project required the development of a custom liquid chromatography-mass spectrometry method for plasma drug concentration monitoring, and it pushed the team to invest in instrumentation and documentation practices that went well beyond routine diagnostics. The trial ran for eighteen months. The experience of working to ICH E6 Good Clinical Practice standards changed how the laboratory approached every subsequent project, including its most routine haematology requests.
Today the laboratory operates across two floors, with a dedicated molecular suite, a histopathology processing room, and a separate reception area for patient-facing collections. The team includes six full-time scientists, two part-time consultant pathologists, and a laboratory manager who joined from a national blood service in 2021. Dr. Miriam Calloway still reviews every non-routine result personally before sign-off. The laboratory is accredited and participates in external quality assurance schemes across all major disciplines. New test menu additions are introduced only after a formal validation period, typically three to four months.
Processed on a Sysmex XN-3000 with automated five-part differential. Any abnormal flags trigger a manual slide review by a medical laboratory scientist. Includes haemoglobin, haematocrit, MCV, MCH, MCHC, platelet count, and white cell differential. Results within 24 hours for samples received before 14:00.
Sodium, potassium, chloride, bicarbonate, urea, creatinine, eGFR, glucose, calcium, total protein, albumin, bilirubin, ALT, AST, and alkaline phosphatase. Run on a Roche Cobas c702 platform. Suitable for routine health screening, pre-operative assessment, and medication monitoring. Results within 24 hours.
Electrochemiluminescence immunoassay on a Roche Cobas e602 platform. Reference ranges are age- and sex-adjusted. Results include a brief interpretive comment when values fall outside the reference interval. Turnaround 24 hours.
Qualitative multiplex PCR covering influenza A B, RSV, SARS-CoV-2, and four additional respiratory viruses. Nasopharyngeal swab in viral transport medium required. Collection kits available at reception. Run on a Bio-Rad CFX96 platform. Results within 6 hours of sample receipt during operating hours.
ANA by indirect immunofluorescence on HEp-2 cells, with reflex to anti-dsDNA, anti-Sm, anti-Ro, anti-La, and anti-Scl-70 if ANA is positive at 1:80 or above. ANCA by ELISA with PR3 and MPO specificity. Rheumatoid factor and anti-CCP included. Turnaround 3-5 business days.

We run fewer tests, run them correctly, and report them honestly.Every sample is logged, temperature-monitored, and processed within a defined window. We reject specimens that fall outside our acceptance criteria rather than run a compromised test.
No result leaves our facility without a qualified pathologist or senior scientist signing off. Automated flags are a starting point, not a conclusion.
We publish realistic turnaround windows and notify you if anything changes. Routine panels: 24-48 hours. Specialised assays: 3-5 business days. We do not promise what we cannot deliver.
A full blood count is one of the most commonly requested laboratory tests, and one of the most frequently misunderstood. The report arrives with a column of numbers, reference ranges, and occasional flags, and it is not always obvious what to do with them. This article explains what each component measures, why values fall outside the reference range, and which findings typically require further investigation.

Answer three questions and we will point you toward the most relevant panel for your situation. This is a starting point, not a clinical recommendation.
For most routine tests, no referral is required. You can request a test directly through our portal or by calling the laboratory. For certain specialised panels, particularly those with clinical interpretation implications, we may ask that a clinician is involved in the request. If you are unsure, call us and we will advise you before you book.
Results are delivered through our secure online portal. You will receive an email notification when your report is ready. The email contains a link only; no result data is sent by email. If you do not have internet access, please let us know when you book and we can arrange an alternative.
For fasting panels (lipid profile, glucose, insulin), please fast for 10-12 hours before your appointment. Water is fine. Avoid strenuous exercise the morning of the test. If you take regular medication, continue as normal unless your prescribing doctor has advised otherwise. Morning appointments are available from 7:30 Monday to Friday.
