Critical Laboratory Results

An urgent result needs an active handover

Some laboratory results may require immediate clinical attention. WHO’s Laboratory Quality Stepwise Implementation tool recommends an established system for notifying the requester promptly when results fall within agreed critical intervals. It also addresses continuing attempts when the initial contact fails and keeping a verifiable notification record. [1]

The system should be designed before a critical result occurs. Uploading a report to a portal alone may not establish that the responsible clinician has received the alert.

Agree on the clinical pathway

Critical limits should be appropriate to the test, patient group and service, with clinical consultation. [1] Copying an internet threshold table without considering the laboratory’s setting may create confusion.

Identify who is authorised to notify, whom to contact and what happens outside routine hours. Keep contact details current and establish escalation routes for unanswered calls.

Communicate the right information to the right person

My recommended handover identifies the patient, sample time, test, result, units and relevant limitations. Confirm that the recipient is the appropriate person for the patient and ask them to repeat the key details back where required by the communication procedure.

WHO reporting guidance emphasises verifying that the correct clinician receives and records the correct patient’s results. [2]

Make notification traceable

Document the communication time, the people involved, the information conveyed and unsuccessful contact attempts. If a corrected result is issued, make the revision and related communication clear.

The record should show what actually happened. An attempted call and a completed handover are different events and should be distinguishable.

Test the process in practice

Review a small sample of alerts to see whether the intended recipient was reached and where delays occurred. Use the findings to improve contact lists, escalation and staff training.

Critical result communication connects laboratory measurement with clinical action. A defined, rehearsed process helps prevent an urgent finding from becoming an unread report.

Peripheral Blood Smear After a CBC

Counts and appearance provide different information

A complete blood count measures blood cell parameters. A peripheral blood smear, also called a blood film, allows examination of cell appearance. It can add information about size, shape, staining and the types of cells present. [1,2]

A request for a smear does not mean the automated analyser has failed. The two investigations can contribute different information to the same clinical question.

Why a smear may be requested

Microscopic review may help assess an abnormal count, investigate a suspected blood disorder or look for particular findings such as blood parasites when clinically indicated. The report must be considered with the history and other investigations. [1]

For patients, ask what question the additional examination is intended to answer. Avoid assuming that a smear request necessarily means cancer is suspected.

Read the descriptive language in context

Terms describing red cell size or shape are observations. Their significance depends on the overall pattern and clinical setting. Several conditions can share morphological features, so one descriptive word should not be treated as a complete diagnosis. [1,2]

Keep the smear report with the corresponding CBC, including the sample date. This helps the clinician relate morphology to the measured counts.

What should the next discussion cover

Ask whether the findings explain the original concern and whether targeted investigations are needed. If you already have previous reports, bring them so the clinician can review the trend.

For referring professionals, provide the reason for testing and relevant illness or treatment history. A focused request helps the laboratory direct attention to the clinical question without restricting appropriate assessment of the rest of the film.

Use the result to guide a decision

The useful outcome is a clearer interpretation and a plan. The additional investigation should help decide whether to observe, investigate further or arrange specialist review. Understanding that purpose is more helpful than reading individual terms from the report without context.

A Low Platelet Count

Interpret the number with the patient

Platelets contribute to blood clotting. A lower-than-expected count is called thrombocytopenia, but the cause and clinical significance cannot be determined from the number alone. Platelet investigations may form part of the assessment of bleeding or other illness. [1]

Bring earlier counts, the full CBC and information about recent illness, medicines or treatment to the consultation. A dated sequence is more useful than one isolated photograph of a result.

Confirmation can be important

In some samples, platelets clump in the presence of EDTA and an automated result may be falsely low. An established laboratory clumping protocol can involve examining the sample and comparing an appropriately collected citrate sample with the EDTA sample. OHSU describes such a protocol for resolving pseudothrombocytopenia. [2]

This possibility should prompt appropriate laboratory review, not an assumption that every low count is an artefact. Verification and urgent clinical assessment may need to proceed together.

Symptoms change the urgency

Bleeding, unexplained bruising or pinpoint skin spots are among symptoms associated with platelet problems. [1,3] Active or substantial bleeding, neurological symptoms or a patient who is acutely unwell requires urgent assessment.

Do not delay care while waiting for repeated testing to produce a preferred number. Likewise, do not independently change medicines or decide on transfusion from a general online article.

Ask focused questions

For patients: Has the result been checked? What does it mean with the rest of my blood count? What follow-up is needed, and which symptoms should make me seek help immediately?

For clinicians: Is there a relevant analyser or specimen comment? Does the count fit the clinical picture? What confirmation and communication are required now?

A reliable plan addresses both questions: whether the laboratory value accurately represents the sample and what the patient’s condition requires. Neither should be used to postpone the other when the situation is urgent.

Professional Indemnity for Dentists

Read the cover against your actual work

Professional indemnity should be considered with a clear description of the services you provide. A policy name or a low premium cannot, by itself, establish whether a particular claim will be covered.

Insurer information illustrates an important distinction: some professional indemnity arrangements operate on a claims-made basis, with conditions concerning when the event occurred, the retroactive period and when the written claim was first made. [1,2] The actual policy wording controls the cover.

Ask about the activities being insured

Give the insurer an accurate description of your practice. Ask specifically about your procedures, specialist work, locations, teaching or consultation roles and work performed through a clinic entity. Obtain the response in writing where it affects the proposed cover.

Do not assume that cover for an individual dentist automatically answers every question about staff, associates, visiting specialists or the organisation itself.

Compare more than the headline limit

My suggested discussion checklist includes the limit for one claim or event, the overall period limit, deductibles, defence costs and relevant exclusions. Ask whether defence costs sit within or outside the stated limit and what consent is required before appointing advisers or agreeing to a settlement.

These questions identify terms to clarify; they are not a statement that every insurer uses the same structure.

Understand continuity and notification

Ask how the retroactive date is treated at renewal or when changing insurer. Clarify what happens after retirement or stopping a particular service and whether any extended reporting arrangement is available.

Read the notification conditions. If a complaint or circumstance arises, check the policy and seek insurer guidance promptly rather than making assumptions about reporting requirements.

Keep the paperwork usable

Store the schedule, wording, proposal disclosures, endorsements and renewal records together. Review the arrangement when the scope of work changes.

Indemnity is one part of professional risk management. It should accompany sound care, communication and documentation. For a specific purchase or claim, obtain advice based on the complete policy and your circumstances.

Missed Oral Cancer

Review the diagnostic pathway

When oral cancer is diagnosed after earlier consultations, the chronology deserves careful review. The later diagnosis alone does not establish what was apparent at each earlier visit or whether the standard of care was breached.

Jacob Mathew v. State of Punjab, (2005) 6 SCC 1, explains that an error or adverse outcome does not automatically establish professional negligence and distinguishes civil from criminal negligence. [1] The case is a foundation for reasoning, not an automatic answer to every later dispute.

Make the original findings clear

My recommended clinical record describes the lesion’s site, duration, appearance, relevant history and examination findings. Record the working diagnosis, important uncertainty and the reason for the chosen investigation or review plan.

A note saying only “ulcer gel advised” may leave the next clinician without the information needed to understand the assessment. Describe what was evaluated and why the next step was selected.

Act on concern

ADA guidance supports timely biopsy or referral for suspicious oral mucosal abnormalities and reassessment of unresolved lesions. [2] It is clinical guidance, not an Indian statute; its relevance should be considered with the individual circumstances and applicable professional standards.

If referral is advised, record its purpose and urgency. Tell the patient whom to contact and what to do if the appointment is not arranged.

Follow up the unresolved question

A useful practice system tracks whether the investigation occurred, whether the report arrived and whether the result was discussed. If the report does not explain the clinical picture, arrange further review rather than assuming the diagnostic process has ended.

Record attempted contacts and patient decisions accurately. Avoid retrospective alteration of the original record.

Learn from a fair review

If concern about delay arises, preserve the chronology and obtain appropriate expert advice. Review communication, access, referral and result-handling processes as well as individual decisions.

The purpose is to identify what can be improved while assessing responsibility fairly. A strong pathway makes the clinical concern, the next action and the person responsible visible at every stage.
