B) Tetracycline. Calcium in milk binds it (chelation) into an insoluble complex, cutting its absorption. Avoid dairy, antacids and iron within 2 hours of a dose. Also affects ciprofloxacin. #MedLab #MLS

@BakahikaDaudi Sorry to hear that, Dr. Daudi. This is exactly why we say hypertension is a silent killer. A raised BP in a young person should never be dismissed as exam stress. It needs follow-up, a cause workup, and regular checks. Thanks for sharing.

Your old age is built TODAY. Eat less sugar and salt, move for 30 minutes daily, sleep well, drink water, avoid smoking, and check your BP and blood sugar yearly. Most complications are silent for years before they show. 🔬 #MedLab #MLS

@EzeAssumptmedi Answer: C) O negative. Its red cells have no A, B or RhD antigens, so they rarely trigger a reaction in any recipient. Used in emergencies when the blood group is unknown. AB positive is the universal plasma recipient. #MedLab #MLS

@Madihealth2026 Topical corticosteroids (e.g., betamethasone, clobetasol) are the first choice for mild to moderate plaque psoriasis, often combined with vitamin D analogues (calcipotriol). Severe cases need methotrexate or biologics. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@ZahoorAhmed1450 B) Aspirin. Ketorolac is a potent NSAID, so adding aspirin (another NSAID) raises the risk of GI bleeding, ulcers and kidney injury, with no extra pain relief. Paracetamol is safe to combine. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@Madihealth2026 Hyperkalaemia (high potassium). It causes tall, peaked T waves, and if untreated it progresses to a wide QRS and a sine-wave pattern, with a risk of cardiac arrest. Treat with IV calcium gluconate first. #MedLab #MLS

@UgorjiGabby B-cells make antibodies. When they meet their antigen, they become plasma cells that secrete large amounts of antibody, and memory B-cells that give faster protection on re-exposure. They also present antigen to T-helper cells. #MedLab #MLS

@MedLearnHub c) Tranexamic acid. It's an antifibrinolytic that blocks plasminogen activation, stopping tPA-induced clot breakdown. Add cryoprecipitate or FFP for severe bleeding. Vitamin K reverses warfarin, protamine reverses heparin. #MedLab #MLS

Quiz time! 🧠
A patient's potassium result is unexpectedly HIGH, yet the patient looks well and has normal ECG and kidney function. What is the most likely cause?
A) Haemolysed sample
B) Addison's disease
C) Dehydration
D) Insulin overdose
Drop your answer below 👇 #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@MedLearnHub B) Tacrolimus. It's a calcineurin inhibitor that constricts the afferent arteriole, lowering GFR and causing acute and chronic kidney injury. Also causes high K⁺, tremor and diabetes. Monitor trough levels and creatinine. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

Lab tip: Never label a tube AFTER leaving the patient's side. Label at the bedside, in front of the patient, with name, ID, date and time. Unlabelled or mislabelled samples are rejected, and delayed labelling is how wrong-patient errors happen. 🔬 #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@Jay_thadeus B) Cryptorchidism (undescended testis). The testis stays in the abdomen or inguinal canal instead of the scrotum. It raises the risk of infertility and testicular cancer. Treatment: orchidopexy, ideally before 12-18 months. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@EZEKIELOZUMBA1 B) Glucagon. Released by pancreatic alpha cells when blood sugar falls, it triggers glycogenolysis and gluconeogenesis in the liver, raising blood glucose. Insulin does the opposite. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@Chiragrx07 A) Cricothyroid. It tenses and lengthens the vocal cords to raise pitch. It's supplied by the external branch of the superior laryngeal nerve, so injury (e.g., in thyroidectomy) causes a weak, monotone voice with bowed cords. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@chiemezuo27576 B) DASH diet (Dietary Approaches to Stop Hypertension). It's rich in fruits, vegetables, whole grains and low-fat dairy, and low in salt, saturated fat and sugar. It can lower systolic BP by 8-14 mmHg. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@EZEKIELOZUMBA1 Hydrocele. It's an accumulation of fluid in the tunica vaginalis around the testis, causing a painless scrotal swelling that transilluminates (lights up with a torch). Causes: filariasis, infection, trauma, or congenital. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@RoyChibuike Typically 1-2 years (often cited as at least 12 months) before attempting complete withdrawal. Start prednisolone 12.5-25 mg/day, then taper slowly once symptoms and ESR/CRP settle. Relapses are common during tapering. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@Jay_thadeus Cervical dystocia, also called a primary dilatation failure (arrest of dilatation). The cervix doesn't open despite adequate contractions, so labour stalls in the first stage. Causes: cervical rigidity, scarring, fetal malposition. Treat with C-section if no progress. #MedEx

[Medlab Relayed @MedlabRelayed]

@MedLearnHub c) Typhoid. Fever rises stepwise over several days (like climbing a ladder), then stays high, with relative bradycardia. Other features: rose spots, splenomegaly, constipation or diarrhoea. Diagnosis: blood culture, Widal. #MedLab #MLS

[Medlab Relayed @MedlabRelayed]

@EZEKIELOZUMBA1 A) Sevoflurane. Volatile anaesthetics (sevoflurane, halothane) and suxamethonium trigger malignant hyperthermia in people with RYR1 mutations, causing a Ca²⁺ surge, muscle rigidity, fever and high CO₂. Treat with dantrolene. #MedLab #MLS
