One question, placed first: this NU566 Unit 7 letter asks hematology whether three months of persistent lymphocytosis with clonal B cells mean early-stage chronic lymphocytic leukemia that needs only monitoring.

[Hematology Clinic], [date].
Re
Mr. [H.], 49, date of birth [DOB], record number [MRN].
Question
Does Mr. [H.] have early-stage chronic lymphocytic leukemia that needs monitoring only, and if so, at what interval should we check his counts in primary care?
Urgency
Routine, within [4 to 6] weeks. He is well, with normal hemoglobin and platelets and no enlarged nodes, liver or spleen. International guidelines reserve treatment for active disease, such as falling blood counts, symptomatic enlargement of nodes or spleen, or disease-related symptoms, and recommend observation for early-stage disease without those features (Hallek et al., 2018). If his counts or examination change before he is seen, we will call.
Clinical Evidence
Absolute lymphocyte count: [7.8], [7.4] and [8.1] x 10^9/L on three counts over three months, first found on a routine blood count for a life insurance application.
Peripheral smear: small, mature-appearing lymphocytes with smudge cells.
Flow cytometry of peripheral blood: a clonal B-cell population, kappa-restricted, expressing CD5, CD19, CD20 (dim) and CD23, with a clonal B-cell count of [6.4] x 10^9/L. That count is above the threshold of 5 x 10^9/L that separates chronic lymphocytic leukemia from monoclonal B-cell lymphocytosis (Hallek et al., 2018; Strati & Shanafelt, 2015).
Hemoglobin [14.6] g/dL; platelets [238] x 10^9/L; neutrophils normal.
Examination: no palpable lymph nodes in the neck, axillae or groin; no liver or spleen enlargement.
Symptoms: none. No fevers, night sweats, weight loss or fatigue. No recurrent infections.
Other: normal kidney and liver function. Hepatitis B and C and HIV serologies [negative].
Medications and Allergies
[Lisinopril] for hypertension. No allergies. A CT scan was not ordered, because imaging is not required for staging early disease without symptoms (Hallek et al., 2018) and we preferred to leave that decision to you.
Shared Care
We ask you to confirm the diagnosis and stage, advise whether any further tests are needed now, and discuss prognosis and the watch-and-wait approach with him. We will keep his vaccinations current, including influenza, pneumococcal and recombinant zoster vaccines, avoid live vaccines as you advise, continue age-appropriate cancer screening, including skin checks, and repeat his blood count at the interval you recommend. We will contact you if his counts rise quickly, if his hemoglobin or platelets fall, or if new nodes or symptoms appear.
Sign-Off
[Name], [credentials], [Practice]. Direct line: [phone]. I will next see Mr. [H.] on [date], [8] weeks from today, and will follow him in the meantime.
Documentation of referrals often lacks the question and the reason for the referral, and specialists frequently report receiving too little information to act (Gandhi et al., 2000). This letter is written to avoid both gaps.

How this NU566 Unit 7 example is structured
The letter follows the order a busy specialist reads in. Question first, stated so it could be answered yes, no or with a specific recommendation. Urgency second, justified by the iwCLL guidelines, which reserve treatment for active disease and make the timing of a first hematology visit a matter of judgment rather than emergency. Clinical evidence third, limited to what bears on the question, so the specialist can judge whether diagnostic criteria are met and what stage applies without reading a full history. Medications and allergies fourth, with the one test deliberately not ordered explained in a sentence. The shared-care paragraph comes next, dividing responsibilities between the two clinicians so nothing falls between them. The sign-off gives a phone number and states when the referring clinician will next see the patient, which tells the specialist where the patient is being followed in the meantime.

NU566 Unit 7 questions, answered
How long should a referral letter be?
One page is usually enough and often preferred. Specialists read many referrals, and a letter that states its question in the first paragraph and supports it with a handful of relevant findings gets a faster, more useful reply. If your rubric asks for more, add it in labeled sections after the question rather than before it.
Is referring a patient a sign that primary care could not manage?
No, and the letter should not read that way. Referral is a judgment about which question needs another clinician's expertise. A well-written letter shows what primary care has already worked out, what it will continue to manage, and the one thing it needs help answering, which is exactly the competence this assignment is testing.
Should the letter recommend a treatment to the specialist?
Generally not. It can say what has been tried or withheld and why, but the specialist decides on specialty treatment. Framing the question well, such as whether disease-modifying therapy should start, invites the recommendation without presuming it. Include allergies and current medications so the specialist can answer safely and without a second round of questions.
